A capacity control valve is provided with a throttle valve portion having a communication hole and a second valve hole. The communication hole is provided between a second valve portion and a third valve portion and makes an intermediate communication passage communicate with a third valve chamber. The second valve hole is provided between a second valve chamber and the third valve chamber. An amount of narrowing of the throttle valve portion in relation to a stroke of a valve element is set larger when the second valve portion initially opens by separating from a second valve seat face, and then becomes narrower after the initial opening of the valve. The capacity control valve is capable of shortening a start-up time and improving the operating efficiency of a variable capacity compressor.

This document discloses a valve comprising a main valve closure body, arranged on a low pressure side of the valve and moveable to open towards the low pressure side, a control body, fixedly connected to the main valve closure body, such that a position of the main valve closure body is fixed relative to a position of the control body, a control chamber, partially defined by the control body, whereby a volume of the control chamber is variable in relation to the position of the control body, and a control fluid connector for controlling a pressure in the control chamber. The document also discloses use of the valve in a separator for separating dust and debris from an airflow, a separator comprising such a valve and a method of operating a separator.

A valve (10) including a first port (12), a second port (14), a third port (16) and a flexure (30), the flexure (30) being moveable between a first position which causes the first port (12) to open, a second position which causes the second port (14) to open, and a third position which causes the first and second ports (12, 14) to close, wherein at least a part of the flexure (30) is magnetisable, to provide a first magnet (32), a second magnet (34) is associated with the first port (12) and a third magnet (36) is associated with the second port (14). A valve assembly includes a pair of valves wherein only one of the valves is operable at any given time.

A solenoid valve including a non-sliding plunger assembly. The solenoid valve disclosed herein generally includes a plunger assembly that is moveably suspended within an internal chamber of a housing of the solenoid valve away from any sliding contact with adjacent surfaces. The plunger assembly may not be in sliding contact with any of the adjacent surfaces, and thus a radial gap may be defined between the plunger assembly and all non-moving, non-flexing features and surfaces of the solenoid valve. The solenoid valve may include a flexural washer that is resiliently flexible and is configured to enable selective axial movement of the plunger assembly in response to energizing the solenoid coil. In various embodiments, the flexural washer is configured to moveably suspend the plunger assembly within the internal chamber away from any sliding contact with adjacent surfaces.

Disclosed is a capacity control valve includes a valve housing. A main valve including a valve body is driven by a solenoid, and a main valve seat which is between a discharge port and a control port and with which the valve body can contact, a pressure sensitive valve member forms a pressure sensitive valve, together with a pressure sensitive body disposed in a pressure sensitive chamber. The control port and a suction port communicate with each other through an intermediate communication passage by opening and closing of the pressure sensitive valve. The pressure sensitive valve member has a through-hole communicating with the intermediate communication passage, and has an opening and closing member attached thereto such that the opening and closing member is restricted in movement with respect to the valve housing by restriction device and slides relative to the pressure sensitive valve member to open and close the through-hole.

A capacity control valve includes a valve housing. A main valve including a valve body is driven by a solenoid, and a main valve seat which is provided between a discharge port and a control port and with which the valve body 51 is allowed to contact. A pressure sensitive valve member forming a pressure sensitive valve with a pressure sensitive body is disposed in a pressure sensitive chamber. The control port and a suction port communicate through an intermediate communication passage by opening the pressure sensitive valve. A slide valve body slides relative to the pressure sensitive valve member to open and close a through-hole communicating with the intermediate communication passage. The slide valve body partitions the pressure sensitive chamber into a Pd side space and a Pc side space, and a Pd-Pc flow passage providing communication between two spaces and is formed in the slide valve body.

A device for regulating the flow of a fluid comprises a valve housing having at least two valve ports, at least one valve seat, a valve member having a closing body, and an actuating unit for actuating the closing body. The valve member further comprises an actuation section, which is connected via at least one connecting web to the closing body for moving the closing body.
