A cable accessory for injecting fluid into a cable. The accessory has first and second ends configured to be coupled to the cable and an external cable accessory, respectively. The accessory has an injection port configured to introduce the fluid to a stranded conductor of the cable. The accessory may include a body and conductive rod. The body defines a through-channel configured to receive the conductor. The rod has a first portion that extends outwardly from the second end to be received inside the external cable accessory and to form an electrical connection therewith. The rod has a second portion configured to be coupled to the conductor and form an electrical connection therewith. The second portion (with the conductor coupled thereto) is positionable inside the through-channel with the first portion extending outward from the second end. The fluid is injectable into the conductor through injection port, which extends into the through-channel.

A valve assembly comprising: a fluid flow passage to permit the flow of a fluid through the valve assembly; a valve seat; and an actuator assembly. The actuator assembly comprises: a valve member moveable relative to the valve seat between a first position in which the valve member is at least partially engaged with the valve seat to at least partially block the fluid flow passage, and a second position in which the valve member is remote from the valve seat; an actuator body in a fixed position relative to the valve seat; and a metal bellows that is attached to the valve member and to the actuator body and is disposed within the fluid flow passage. The valve member of the actuator assembly is moveable relative to the actuator body and extends around the actuator body such that the actuator body is disposed within the valve member.

A check valve unit 1 includes: a container body 2 including a valve body housing portion 21, a valve seat 22, and a protruding portion 23, the valve body housing portion 21 having a cylindrical shape, the valve seat 22 being formed at one end portion of the valve body housing portion 21 and protruding from an inner peripheral surface of the valve body housing portion 21, the protruding portion 23 being formed at the other end portion of the valve body housing portion 21 and protruding from the inner peripheral surface of the valve body housing portion 21; and a valve body 3 including a valve portion 31 and a guide portion 32 and disposed in the container body 2, the valve portion 31 coming into contact with the valve seat 22 at a time of preventing backflow of refrigerant, the guide portion 32 including a plurality of blades.

Valves and valve assemblies are described herein employing architectures which can mitigate degradative wear mechanisms, thereby prolonging life of the assembly. In one aspect, a valve comprises a head including a circumferential surface and a valve seat mating surface comprising sintered cemented carbide. Leg members extend from the head, wherein thickness of one or more of the leg members tapers in a direction away from the head to induce laminar fluid flow around the head. In some embodiments, the sintered cemented carbide is an inlay coupled to the valve head.

A compressed air drying system includes a forced-induction device, a compressor to which the forced-induction device is connected, a removal device that performs a loading mode operation and an unloading mode operation, a pressure regulating device that opens and closes a drain valve device using air pressure, and a check valve, which includes a body and a piston. The body has a first port connected to the compressor, a second port connected to the removal device, and a third port connected to the pressure regulating device. The piston is slidably arranged in the body. The hardness of the material of a slidable-contact portion of the body that slidably contacts the piston is different from the hardness of the material for the piston.

A cable accessory for injecting fluid into a cable. The accessory has first and second ends configured to be coupled to the cable and an external cable accessory, respectively. The accessory has an injection port configured to introduce the fluid to a stranded conductor of the cable. The accessory may include a body and conductive rod. The body defines a through-channel configured to receive the conductor. The rod has a first portion that extends outwardly from the second end to be received inside the external cable accessory and to form an electrical connection therewith. The rod has a second portion configured to be coupled to the conductor and form an electrical connection therewith. The second portion (with the conductor coupled thereto) is positionable inside the through-channel with the first portion extending outward from the second end. The fluid is injectable into the conductor through injection port, which extends into the through-channel.

A fitting for injecting a first fluid into an injection port of a cable accessory. The fitting includes at least one seal positioned on an injection nozzle. The nozzle is configured to be inserted into the port and has an internal fluid passageway through which the first fluid is injected into the accessory. The seal forms at least one fluid tight seal between the nozzle and the port. The fluid tight seal prevents the first fluid from exiting the accessory and flowing into an outer portion of the port and prevents a second fluid from flowing into an inner portion of the port. The first and second fluids have first and second voltage potentials, respectively. The second voltage potential is different from the first voltage potential. The seal isolates the first and second voltage potentials by isolating the first fluid from the second fluid.

An oil tank for a gas turbine engine includes a top and a bottom disposed vertically beneath the top. An overfill return passage extends from the bottom of the oil tank toward the top of the oil tank. An outlet is formed on the bottom of the oil tank and inside the overfill return passage. A check valve is inside the overfill return passage and is connected to the outlet. The check valve includes a seat circumscribing the outlet and a plug inside the overfill return passage. The plug has a lower density than an oil disposed inside the oil tank. The check valve does not include a spring such that the plug is configured to translate freely inside the overfill return passage.

The valve device includes a main member for installing on a toy gun and connecting to a high-pressure gas source. Inside the main member, there is a first chamber, a second chamber connected to the first chamber, and an inlet channel. A valve member is movably housed in the main member. The valve member includes a valve channel, a through hole, an inlet blocking element, and an outlet blocking element. The valve member selectively blocks the connection between the first chamber and the inlet channel. As such, the pressure difference between the second chamber and the high-pressure gas source drives the valve member to selectively block the inlet channel, without using a spring to control the valve member. The valve device therefore has enhanced operation life and reduced cost.

Flow control valves may be positioned downstream of water meters to increase pressure and compress entrained water vapour passing through the meters. However, turbulence within such valves can cause the valve's head to move radially, bending a shaft within the valve which may break. Accordingly, there is provided a flow control valve comprising: a housing having a flow passage; a valve seat defined within the flow passage; a valve head moveable to a closed position to engage the valve seat and seal the flow passage; a shaft secured to the valve head; a support slidingly mounting the shaft within the housing; a spring biasing the valve head to the closed position and configured to maintain the valve head in the closed position until a predetermined pressure is applied; and a guide assembly extending along at least a portion of the flow passage to constrain radial movement of the valve head.
