摘要:
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.
摘要:
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.

A butterfly valve (100) and a valve system using the butterfly valve are disclosed. The butterfly valve includes a valve body (102) and a valve disk (112) 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.

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.

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.
