A modular valve assembly is formed from multiple modular valves having a valve base and a valve actuator. Each base includes at least a first channel and a second channel and an internal passage forming an opening in the first channel so as to be in selective fluid communication with an exterior port of the valve base, and with the second channel being a through passage that is not in fluid communication with the internal passage. Adjacent valve bases are interconnectable in one of two orientations either with the first and second channels of one valve base being aligned with the first and second channels, respectively, of an adjacent valve base, or with the first and second channels of one valve base being aligned with the second and first channels, respectively, of an adjacent valve base. The valve bases may be provided with third and fourth channels for three-way operability.

A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular manifolds allows for expansion or modification of the manifold assembly to control a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

The present invention aims to provide a valve driving device that suppresses an increase in size and improves thrust. The present invention includes a bobbin including a body portion, a solenoid coil wound around the body portion of the bobbin, an armature arranged on a radially inner side of the bobbin and fixed to a rod, an anchor that covers one side in an axial direction of the armature at a position on the radially inner side of the bobbin, a yoke partially arranged between the bobbin and the anchor, and a cylindrical member arranged between the bobbin and the armature. The bobbin includes a recessed portion on the radially inner side, and a part of the cylindrical member is inserted into the recessed portion. A part of the cylindrical member and the recessed portion are arranged so as to be laminated in the radial direction.

A valve device includes a valve block having a valve port through which a fluid passes and an insertion hole; a moving valve body that opens or closes the valve port; a guide member that is inserted in the insertion hole, and slidably guides the valve body; a solenoid that generates a magnetic field when energized; a stationary pole that cooperates with the solenoid to move the valve body; a tubular support member that is inserted in the insertion hole to accommodate the solenoid, and supports the guide member that receives pressure from the fluid passing through the valve port; and a lid member that closes an opening of the support member, and the support member is joined with the valve block.

A valve (1) for controlling a flow of a fluid comprises: – a valve body having at least one first body part (2) made of a moulded plastic material; – a chamber for passage of the fluid (6), defined within the first body part (2) and comprising at least one fluid inlet (6a) and at least one fluid outlet (6b); – a valve seat (7) defined within the chamber for passage (6) of the fluid; – means for shutting off the fluid (8-9), which can be displaced relative to the valve seat (7) in order to control flow of the fluid; and – a compensation element prearranged for compensating a possible increase in volume and/or pressure of the fluid. The compensation element comprises a compensation body (26) made of an elastically deformable and/or compressible material, the moulded plastic material of the first body part (2) being stiffer than the elastically deformable and/or compressible material. The first body part (2) defines a tubular portion (23) that extends between the valve seat (7) and one of the inlet (6a) and the outlet (6b), within the chamber for passage of the fluid (6). The compensation body (26) is mounted within the chamber for passage of the fluid (6) so as to surround the tubular portion (23) at least partially.

An EGR valve includes: an inner housing including a flow passage; a valve element which opens and closes the flow passage; a valve shaft on which the valve element is provided; an outer housing in which the inner housing is assembled; and a drive unit which drives the valve shaft. The flow passage of the inner housing includes an inlet and an outlet. The outer housing includes an assembly hole and separate flow passages. When the inner housing is assembled in the assembly hole, the inlet and the outlet of the inner housing communicate with the separate flow passages of the outer housing; an inlet sealing member is provided between the inner housing and the outer housing to correspond to the periphery of the inlet; and an outlet sealing member is provided between the inner housing and the outer housing to correspond to the periphery of the outlet.

To provide an electromagnetic valve capable of preventing damage due to stress of a buffer member. An electromagnetic valve includes a solenoid having a case, a flow path member, and a columnar valve element that is housed in the valve element housing portion of the flow path member and moves with a plunger of the solenoid to open and close a flow path. A seat member with which the plunger comes into contact is disposed in the case of the solenoid. The seat member includes a core portion with which the plunger comes into contact, and a plurality of protruding portions protruding radially outward from an outer peripheral surface on the radially outer side of the core portion.

The disclosure relates to a sensor cleaning system for a vehicle having: at least one sensor cleaning module, wherein the sensor cleaning module has a valve unit, wherein the valve unit is configured for receiving compressed air via a module compressed air port and for selectively outputting the compressed air cleaning pulse via a cleaning compressed air port. The sensor cleaning module has a module reservoir and a pump mechanism, wherein the module reservoir is configured for receiving and storing the cleaning liquid provided via a module liquid port, and is connected to the pump mechanism for fluid transfer, and the pump mechanism is configured for providing the cleaning liquid in the form of a liquid cleaning pulse at a cleaning fluid port depending on a control signal.

A cleaning device for a vehicle provides a liquid cleaning pulse and/or a compressed air cleaning pulse for a cleaning nozzle. The cleaning device includes a module compressed air connection for receiving compressed air and a pressure cylinder with a cylinder volume. A movable separator divides the cylinder volume into a compressed air receiving chamber and a cleaning liquid receiving chamber in a fluid tight manner. The air chamber has an air chamber connection which can be supplied with compressed air. Contraction of the liquid chamber occurs when filling the air chamber by moving the separator against a restoring force. A switching valve establishes a pneumatic connection between the module compressed air connection and the air chamber connection. A bypass valve establishes a pneumatic connection between the module compressed air connection and the compressed air nozzle line while bypassing the switching valve for providing a bypass compressed air flow.
