A solenoid-operated valve assembly that reduces the jet flow of fluid or gas in an axially exiting valve. The valve assembly comprises a spool valve, a valve member housing, and a flow path. The spool valve comprises a fluid communication channel, a tail, and an inlet seat. The valve member housing comprises at least one inlet, at least one nozzle flow director, and at least one outlet. The flow path begins at the at least one inlet and exits at the at least one outlet. The at least one nozzle flow director is within the flow path. The spool valve moves axially within the valve member housing between a closed position and an open position. The inlet seat closes the at least one flow path at the inlet when the spool valve is in the closed position. A method of operation of the solenoid-operated valve assembly is also provided.

Compensation of jet forces in a valve with an axial outlet

An actuator for use with an on/off solenoid configured to maintain a position corresponding to the energized state of the solenoid when the solenoid is de-energized. The actuator is comprised of a guide that rotates a selector between one of two positions each time the solenoid is energized. One position of the actuator places the selector in an extended position and the other position of the actuator places the selector in a retracted position. To move the selector between the first and second positions, the solenoid is momentarily energized, and in each position of the selector, the solenoid is de-energized. The actuator can be coupled to a poppet valve to maintain the valve in one of two positions when the solenoid is de-energized.

Actuator with toothed profile engaging inclined surfaces for solenoid operated valve

A three-port fluid control valve and a valve assembly using the fluid control valve are provided herein. The valve includes a first inlet, a second inlet, and a sealing element to selectably open one inlet to fluid communication with an outlet and to close the other inlet to fluid communication with the outlet. The valve system includes an actuator, for example a solenoid, to provide accurate and responsive control of the position of the sealing element.

Thermal management valve

A rolling-element bearing for an electromagnetic solenoid includes a hollow cylindrical cage with a plurality of spherical pockets formed around a first circumference and a second circumference of the cage. The pockets around the first circumference are offset from the pockets around the second circumference. Spherical rolling elements are provided in the spherical pockets and are captured for free rotation in the first pockets and second pockets.

Linear bearing for an electromagnetic solenoid and solenoid having said linear bearing

Electrohydraulic solenoids with improved filtering of venting fluid are provided herein. In some embodiments, an electrohydraulic solenoid comprises a hollow cylindrical bobbin having a flange at a first end with a core having a cavity open at one end disposed in the hollow of the bobbin. An armature is disposed within the cavity and supported for axial movement within the cavity. A portion of a pole piece is disposed in the hollow of the bobbin at the first end with an axial face of the portion abutting the open end of the cavity and a shoulder axially spaced from the flange forming a gap. A vent path is formed between the cavity and an outer environment, the vent path comprising at least a portion of the gap, with a magnet disposed in a portion of the vent path.

Integration of magnet in solenoid vent path

An electromagnetic solenoid is disclosed. The solenoid includes a coil, a bobbin, a flux sleeve, an armature, and a pole piece, arranged in such a way that the solenoid is robust against misalignment of the pole piece with the flux sleeve. The configuration facilitates the integration of either the pole piece or the flux sleeve into a hydraulic circuit.

Solenoid robust against misalignment of pole piece and flux sleeve

A bypass valve and a valve assembly including a bypass valve are disclosed. The bypass valve includes a manifold having 4 ports and a valve stem including two sealing elements disposed along the valve stem length. The valve stem may be displaced to a first valve position and a second valve position to selectably place combinations of ports in fluid communication with each other.

Bypass valve

A solenoid fluid control valve is disclosed for controlling a variable displacement pump. The solenoid fluid control valve comprises a fixed solenoid component, a movable armature component, a fixed nozzle body, a movable spool within the fixed nozzle body, and a valve member. The valve member regulates fluid pressure in a first and second feedback chamber. Fluid in the second feedback chamber establishes a second feedback pressure that acts on the movable spool with a motive feedback force in a first axial direction. The movable spool moves in the first axial direction in response to the motive feedback force.

Dual/variable gain oil pump control valve

A butterfly valve and a valve system using the butterfly valve are disclosed. The butterfly valve includes a valve body and a valve disk disposed in the body such that the valve disk may be rotated between at least a first position and a second position using a linear actuator. The actuator may be a linear solenoid coupled to the valve disk spaced a distance from the axis of rotation of the valve disk.

Solenoid actuated butterfly valve

A combination thermal management valve for management of the flow of heat transfer media is provided. The thermal management valve includes a manifold including two or more independently controlled valve assemblies configured to fluidly isolate the heat transfer media from each other. The valve assemblies may be configured to maintain desirable flow characteristics for each thermal medium.

Combined thermal management unit

A direct acting solenoid actuator includes an armature and associated push pin that are suspended from certain fixed solenoid components, such as a pole piece and/or flux sleeve, by a fully floating cage of rolling elements. The fixed solenoid component may comprise a pole piece and/or a flux sleeve. The pole piece may include stops to limit movement of the cage of rolling elements in the axial direction.

Direct acting solenoid actuator

A solenoid actuator comprising an armature member that engages a spool including a spool cap on an end of the spool that is axially movable relative to the spool. A bore in the spool allows fluid to flow from a control port to the spool cap, such that pressure is established in the spool cap. The pressure established in the spool cap acts on the spool with a force directly proportional to the control pressure and the fluid-contacting area inside the spool cap.
