A fluid regulating device includes a valve having an inlet and an outlet and an actuator coupled to the valve and having a control assembly. The control assembly includes a control element and a diaphragm operably connected to the control element, the control element disposed within the valve and adapted to be displaced relative to a valve seat. A noise attenuation assembly is coupled to the outlet of the valve and includes a cylindrical body and at least one plate disposed in the cylindrical body, the at least one plate having an outer edge. An apparatus for retaining the noise attenuation assembly includes a plurality of rods coupled to the at least one plate. The plurality of rods includes at least one rod having a first end disposed through the outer edge of the at least one plate to support the noise attenuation assembly.

A solenoid valve has a spool is moved via a rod. A breathing hole penetrates a sleeve in a radial direction and allows an inner space of a housing part to communicate with the outside when at least a circular columnar plunger is in a predetermined region provided on a solenoid case side of the sleeve. A through-hole is formed in an axial direction at the center axis of the circular columnar plunger. The rod is configured such that an opposing groove portion passes through the center of the circular columnar plunger in the radial direction and penetrating penetrates both radial sides provided with cutout portions of the rod formed at an opposing end portion facing a circular columnar plunger side and an inner surface of the opposing groove portion formed in a symmetrical arc shape as viewed in the radial direction.

A pressure reducing valve (IOO) includes a displaceable throttling element (51) displaceable between a fully-open position in which fluid flows along a flow path from an inlet (11) to an outlet (45), and a closed position in which the flow path is blocked. A spring (6) acts to displace the displaceable throttling element to the fully-open position while pressure within a control chamber (54) acts on a pressure-actuated surface to displace the displaceable throttling element towards the closed position. A switchable hydraulic control circuit in fluid connection with the inlet, the outlet and the control chamber, is switchable between first state in which a pressure within the control chamber is equalized with the outlet pressure, and a second state in which the pressure within the control chamber is equalized with an inlet pressure.

Equipment for fluid transfer includes a valve, a frame that defines a housing for the valve and an upstream passage for the fluid that leads into the housing and is fluidically connectable to a fluid source, the valve being able to move between a non-inserted position and an inserted position in which the valve is situated at least partially in the housing, a module that defines a downstream passage for the fluid that fluidically connectable to the reservoir, the module being able to move between an open position, allowing the insertion of the valve, and a closed position in which the module is fixed to the frame, and two seals that are respectively compressed substantially between the valve and the frame and between the valve and the module when the valve is in the inserted position and the module is in the closed position.

A variable orifice flow device controls the flow of a fluid between a volute casing and a compressor motor casing in a compressor. The variable orifice flow device may be a shuttling valve, with positions controlled by, for example, valves controlling the flow of the fluid into a space opposite a side within the shuttling valve assembly. The variable orifice flow device may have one or more orifices through which a fluid can enter the compressor motor casing, and the surface area of the orifices may be controlled by the position of the shuttling valve.

The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.

A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.

In accordance with at least one aspect of this disclosure, a system includes, a first moveable member disposed in a first chamber configured to move between a first position and a second position of the first moveable member to allow or prevent fluid from passing from an inlet of the first chamber to an outlet of the first chamber. A second moveable member is disposed in a second chamber configured to move between a first position and a second position of the second moveable member to allow or prevent fluid from entering a biasing chamber, the second chamber being fluidly connected to the first chamber.

In accordance with at least one aspect of this disclosure, a system includes, a first moveable member disposed in a first chamber configured to move between a first position and a second position of the first moveable member to allow or prevent fluid from passing from an inlet of the first chamber to an outlet of the first chamber. A second moveable member is disposed in a second chamber configured to move between a first position and a second position of the second moveable member to allow or prevent fluid from entering a biasing chamber, the second chamber being fluidly connected to the first chamber.

Some examples include a valve for a printing fluid supply system, the valve including a static portion and a dynamic portion. The static portion includes a stem extending along a longitudinal axis. The stem includes a head, a tail, and a shaft extending between the head and the tail. The dynamic portion is disposed around the stem. The dynamic portion is longitudinally movable along the stem between a closed position and an opened position. The dynamic portion includes a neck and a body extending longitudinally from the neck, the neck to seal around the head in the closed position and fluidly open in the opened position, the body to slidably fluidly seal against a housing between opened and closed positions. A liquid ink pathway and an air pathway are formed between the static portion and the dynamic portion.
