An electromagnetic valve manifold includes an electromagnetic valve including a discharge port, a manifold base including a discharge passage that is connected to the discharge port, and a check valve. The check valve includes a valve member, a valve housing including a valve seat, and an urging member. The valve housing includes a valve chamber that accommodates the valve member, a peripheral wall that defines the valve chamber, a valve hole that connects the valve chamber to the discharge port, and a discharge opening that connects the valve chamber to the discharge passage. The check valve is disposed in the discharge passage. The discharge opening is formed in the peripheral wall, at least a part of the discharge opening overlapping with the valve seat in a direction orthogonal to a moving direction of the valve member.

A high-pressure gas cylinder valve for vehicle includes a valve seat having a gas charging runner and a gas supplying runner. A check valve is connected in series onto the gas charging runner, and the check valve and a solenoid valve are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas. The gas cylinder valve further includes a flow-blocking buffer structure connected in series onto the gas supplying runner and located downstream of the solenoid valve and upstream of an intersection of the gas supplying runner and the gas charging runner.

The present invention provides an unloading valve assembly that configures a compression area divided for each control input and opens a valve seat by a pressurizing rod of a piston that performs pressurization by a control input, thereby quickly and accurately exhausting compressed air through the unloading valve assembly and improving durability when closing the valve.

A novel fluid valve system includes a housing defining a fluid path between first and second ports. The housing preferably includes an interior cylindrically-arcuate surface that defines a center of curvature, with the fluid flow path passing through an opening in the interior cylindrically-arcuate surface. The fluid valve may include a foot having a bottom and a heel, with the bottom facing the interior cylindrically-arcuate surface, and with the heel disposed transverse to the bottom. The foot may extend in a radial direction away from the center of curvature, with the foot pivoting within an operational angular range about the center of curvature. The bottom of the foot may be configured to translate over the opening in the interior cylindrically-arcuate surface, and the heel may be configured to abut the second port with the foot pivoted to a closed position of the operational angular range.

A capacity control valve includes a valve housing; a main valve including a valve body driven by a solenoid, and a main valve seat between a discharge port and a control port and with which the valve body is contactable; and a pressure sensitive valve member disposed in a pressure sensitive chamber and forming a pressure sensitive valve, together with a pressure sensitive body. The control port and a suction port communicate with each other through an intermediate communication passage by opening the pressure sensitive valve. The pressure sensitive valve member has a through-hole communicating with the intermediate communication passage and has a slide valve body attached thereto such that the slide valve body slides relative to the pressure sensitive valve member to open and close the through-hole. A biasing device is provided on a radially outer side of the slide valve body.

Provided is a valve assembly for a gas vessel including: a valve body mounted at an inlet of the gas vessel and connected to a gas supply source; a connection part connected to the gas supply source on a side surface of the valve body; a check valve mounted on the connection part; and a safety valve mounted on the side surface of the valve body to discharge a fuel gas in the gas vessel to the outside when a gas pressure inside the gas vessel increases above a certain pressure or higher. The valve assembly for a gas vessel is connected to the lower end of the valve body and arranged in the gas vessel to block the gas passage when the fuel gas introduced through the valve body is charged to a set value to prevent overcharging of the fuel gas.

A male joint includes a male joint main body and a valve element provided coaxially with a central axis of the male joint main body. The valve element includes a shaft portion and a valve portion coaxially provided at a tip end of the shaft portion. The valve portion has a first surface intersecting with the central axis and a second surface that is connected to an outer edge of the first surface and extends along the central axis from the first surface to a base end at a base end portion. The valve portion further comprising a groove having an annular shape centered on the central axis at a side portion and a deformation portion on a base end side of the groove.

The invention relates to a valve apparatus (10) for vacuum applications, comprising a valve housing (20) which delimits a valve chamber (22), the valve chamber comprising a vacuum supply opening (28), a suction opening (32), and a ventilation opening (36); comprising a valve body (40) which is arranged in the valve chamber and can be displaced along a switching axis (38) between a suction position and a ventilation position, wherein the valve body in the suction position closes the ventilation opening and in the ventilation position closes the vacuum supply opening; comprising a bistable actuator (50) for driving a displacement movement of the valve body, the actuator comprising an armature (52), connected to the valve body, and an electromagnetic coil (54) for driving a displacement movement of the armature; and comprising a swing check valve (74) for opening and closing the vacuum supply opening (28). The invention also relates to a vacuum handling apparatus (100) comprising a valve apparatus (10).
