A modular valve assembly can include a core spool module and a plurality of end connection modules. The end connection modules can be configured to be secured to the core spool module at one or more of a core inlet or a core outlet of the core spool module to provide one or more respective, different flow configurations for the modular valve assembly. The core spool module can include a bonnet portion that is integrally formed with the core inlet and the core outlet and a seat ring configured to provide a seal against flow of process fluid through the modular valve assembly.

A foil transducer for a valve, including at least one firmly arranged holding part, at least one displaceable force transmission part, an electroactive foil composite structure and at least two electrodes. The electroactive foil composite structure has an actuating direction in which the electroactive foil composite structure is extended on actuation. The actuating direction lies in a plane spanned by the electroactive foil composite structure.

The invention concerns a thermostatic valve (1) comprising a closed hollow body (2), a first opening leading into the hollow body (2), referred to as the inlet opening (4), a second opening leading into the hollow body (2), referred to as the main outlet (5), a third opening, substantially perpendicular to the second opening, leading into the hollow body (2), referred to as the bypass outlet (7), and a seal (11) allowing the inlet opening (4) to be alternately separated from the main outlet (5) or the bypass outlet (7). The seal (11) comprises a thermostatic actuator (12) and a skirt (13) which is made of plastic material and has at least one window (19) suitable for being traversed by a fluid, the skirt (13) being capable of sliding in the hollow body (2), along an axis that substantially coincides with the axis of the thermostatic actuator (12), between a first position in which the skirt (13) seals the main outlet (5), such that the fluid flows between the inlet opening (4) and the bypass outlet (7), and a second position in which the skirt (13) leaves the main outlet (5) open and seals the bypass outlet (7), such that the fluid from the inlet opening (4) can pass through the window (19) and flow through the main outlet (5).

A multi-passage coolant valve may include an outer housing including an outer body formed with a first outer inlet, a second outer inlet, a first outer outlet, and a second outer outlet, and an auxiliary body formed with a third outer outlet, and an inner housing rotatably provided in the outer housing. As the inner housing rotates by a predetermined angle, the first outer inlet and the first outer outlet are fluidly communicated with each other, the first outer inlet and the second outer outlet communicate with each other, and the second outer inlet and the third outer outlet communicate with each other.

A cap assembly includes two caps each pivotable about an axis of a respective pivot rod between an open position and a closed position, the two pivot rods arranged adjacent each other with parallel pivot axes (B) to define a hinge region, each cap having a pivot end extending into the hinge region between the two pivot rods; and a common pivot mechanism arranged to push against the pivot ends, in response to actuation of the pivot mechanism, to pivot the caps substantially simultaneously to the closed position, the common pivot mechanism comprising: a lever; a cam in connection with the lever and located in the hinge region such that actuation of the lever causes movement of the cam in the hinge region along the direction of the pivot axes; a plunger located in the hinge region between the cam and the pivot ends.

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.

A meter bypass assembly includes a housing and a valve assembly. The housing defines a first inlet and a first outlet, and a second inlet and a second outlet. The valve assembly is rotatable to a first position in which fluid is allowed to flow from the first inlet to the first outlet and from the second inlet to the second outlet. The valve assembly is also rotatable to a second position in which fluid is allowed to flow from the first inlet to the second outlet and is restricted from flowing from the first inlet to the first outlet and from the second inlet to the second outlet. The valve assembly includes a shaft extending in a longitudinal direction of the housing and first and second valve bodies rotationally fixed to opposing ends of the shaft.
