A cryogenic valve includes a first port and a second port, a valve body, a valve stem, a sealing member, a valve element and a housing. The valve body includes a valve seat defining a fluid orifice in fluid communication with the first port. The valve stem is configured to engage with the valve body, wherein at least one of the valve stem and valve body form an inner valve cavity. The valve element is positioned within the inner valve cavity. The valve element is also configured to bias the sealing member against the orifice to substantially block flow through the orifice and the first port. The bias is controlled in response to control of the valve element by a valve actuator. A channel is configured to allow fluid flow through at least one of the valve stem and valve element along a longitudinal axis. A housing is configured to substantially seal and enclose at least a portion of the valve body and valve stem. The housing forms an inner housing cavity configured to thermally isolate the exterior of the valve body and valve stem from the housing.

A valve includes a housing that surrounds a fluid outlet, a valve element with a longitudinal axis, a valve seat body that surrounds a fluid inlet and which has a sealing seat such that the valve is closed when the valve element bears against the sealing seat and which is coupled to the housing. The valve element is movable relative to the valve seat body in a direction of the longitudinal axis to enable a fluid flow from the fluid inlet to the fluid outlet, the valve seat body surrounds a guide surface to which the valve element is coupled in order to guide the movement of the valve element, and the valve seat body is formed from a harder material than the housing.

A fixing structure for solenoid (10) includes a valve body (50) including a tubular valve insertion portion (51), a solenoid (10) to be inserted into the valve insertion portion (51), a cover (60) to cover the valve body (50) in a direction intersecting an inserting direction of the solenoid (10) into the valve insertion portion (51), and a pin (40) to be inserted and pierced through the valve insertion portion (51) and the solenoid (10) from the side of the cover (60), thereby restricting detachment of the solenoid (10) from the valve insertion portion (51). The cover (60) includes a resilient pressing piece (61) to be pressed against the pin (40) and resiliently deformed when inserting the pin (40) and to hold an inserted state of the pin (40) by resiliently returning and pressing an end of the pin (40) when the insertion of the pin (40) is completed.

A high pressure valve includes a body on which is fixed an electromagnet, the shell of which has a radial discal part provided with a central hole connecting an internal opposite surface to an external surface. The body is provided with a cylindrical external centring surface and with a radial support surface. The shell is arranged on the body around the centring surface, the external discal surface being in surface contact against the support surface of the body. The coil of the electromagnet is arranged in the tubular space between the body and the shell itself closed by a closure ring. The liquid-tightness between the body and the shell is ensured by a gasket compressed by a wedging washer against the centring surface and against the internal discal surface. The shell is then immobilised on the body by the wedging washer.

An electromagnetic valve for an internal combustion engine includes a housing, an electromagnetic actuator arranged in the housing, the electromagnetic actuator having an electromagnetic armature and a core, a control element which is arranged to protrude axially out of the housing and which is connected to the electromagnetic armature so as to form a movable unit together therewith, the movable unit having a radial recess, and an arrangement which delimits an axial movement of the movable unit away from the core of the electromagnetic actuator. The arrangement includes at least one hook arranged on the housing. The at least one hook engages into the radial recess of the movable unit.

An electrically actuated valve with a hydraulic unit includes a valve housing and at least one electric actuator. Electronics are fastened to the hydraulic unit and at the same time are precisely positioned so that a seal between the electronics and the actuator does not shift or fold over on itself. To this end, a positioning device is formed between the electronics and the hydraulic unit.

A divert-air valve for a compressor of an internal combustion engine includes a flow housing with a duct, an actuator, a control body moved by the actuator to control a throughflow cross section of the duct, an armature, openings in the control body, a valve housing with a housing wall, a support ring with a ring-shaped plate and a cylinder wall, and a sealing ring which seals the housing interior with respect to a part of the duct. The armature is connected to the control body. The openings fluidically connect the housing interior to a part of the duct. The valve housing surrounds the actuator and a part of the control body. The support ring bears, via the cylinder wall, radially from the outside against the housing wall. The radial sealing ring lies axially against the ring-shaped plate and bears radially at the outside against the housing wall.

In at least some implementations, a solenoid valve includes a housing, a bobbin and an armature. The bobbin is received at least partially within the housing and has a body about which a coil is provided. A fluid flow path including an inlet and an outlet and a valve seat is defined by at least one of the housing or the bobbin, and the armature is moveable relative to the valve seat to control flow through the fluid flow path.

A fluid valve use in a turbomachine in a high temperature location includes a fluid inlet, a fluid outlet, a fluid circuit defined between the fluid inlet and the fluid outlet, and a solenoid including a solenoid casing. The solenoid is disposed between the fluid inlet and fluid outlet. The solenoid is configured to move a valve member between a closed position, at least one partially open position (e.g., any number of suitable positions), and a fully open position to selectively meter fluid flow through the fluid circuit. The fluid valve can include a valve casing, wherein the solenoid and valve member are disposed in the valve casing.

A valve assembly for controlling fluid flow rate comprising a valve block, a valve, a sensor chip package, and a controller interface. The valve block having an upstream reservoir, a downstream reservoir, and a valve seat for communicating fluid from an upstream location to a downstream location. The valve having a moveable member. The sensor chip package having at least one sensor coupled with the valve. The controller interface is communicable coupled to a control unit, the valve, and the sensor chip package. The controller interface sends at least one parametric value provided by the sensor chip package to the control unit. The controller interface receives a control signal used to adjust valve stroke of the valve. The control signal of the valve is determined based on the at least one measured parametric value and at least one other parametric value provided by a fluid processing system.
