Abstract: A valve for a heat exchanger includes a base configured to be positioned adjacent to an inlet end of a heat exchanger, a heating element positioned on the base, and a flap connected to the base that is movable between an open position and a closed position. The open position permits the flow of fluid into the inlet end of the heat exchanger and the closed position blocks the flow of fluid into the inlet end. The flap is made from a heat responsive material.

Abstract: A passive in-line valve configured to be actuated without an external control includes a valve housing defining an inlet, an outlet, and a flow path between the inlet and the outlet and a piston housing extending inwardly from the housing. The valve includes a valve piston movably disposed within the piston housing, the valve piston including an upstream side and a downstream side. The valve also includes a control mechanism disposed at least partially within the housing and configured to port outlet static pressure to the upstream cavity in a first state such that pressure is equalized on the valve piston.

Abstract: A valve assembly includes an outer housing having a first opening in fluid communication with a first fluid, a second opening in fluid communication with a second fluid, a third opening in fluid communication with a third fluid and a fourth opening in fluid communication with a fourth fluid. The valve assembly includes a piston configured to slide within the outer housing into a first position at which the third opening is blocked from fluid communication with the fourth opening based on a fluid pressure of the first fluid being greater than a fluid pressure of the fourth fluid. The piston is further configured to slide within the outer housing into a second position at which the third opening is in fluid communication with the fourth opening based on the fluid pressure of the second fluid being greater than the fluid pressure of the fourth fluid.

Abstract: A valve system includes a valve, a valve controller, and a heat exchanger. The valve is configured to open and close a control device in response to a working fluid. The controller controls the flow of the working fluid to and from the valve. The heat exchanger is mounted between the valve and the valve controller. The heat exchanger receives the working fluid from the valve, cools the working fluid using a cooling stream, and delivers cooled working fluid to the valve controller.

Abstract: A ball shaft for a coolant valve includes a body extending from a first end to a second end through an intermediate portion defining an axis of rotation, and a ball section formed on the intermediate portion. The ball section includes an outer surface, an inner surface that forms a coolant receptacle, and a slotted opening extending from the outer surface to the inner surface. The slotted opening includes a width of between about 0.0374″ (0.696 mm) and about 0.0364″ (0.670 mm).

Abstract: A valving system has an actuator member connected to move with an actuator piston and change the position of a valve member. There is a smaller face fluid chamber acting on a small area piston face, and a larger face fluid chamber acting on a larger face of the actuator piston. The torque motor has an armature and a flapper caused to move by current received at the armature. The flapper moves between two fluid ports to control the pressure in the larger face chamber. The flapper further has a positioning extension engaging a first feedback spring operable between it and a forward face of the actuator piston and providing a spring force in combination with a spring force from the positioning extension. A control is operable to provide current to the armature to control the fluid received in the larger face chamber. The controller is programmed to associate the current supplied to the armature to an actual position of the valve member. A method is also disclosed.

Abstract: An inline valve includes a sliding piston having a radially outer stop portion with a forward end. A radially inner sliding portion is connected to the radially outer stop portion by an arm. A housing includes an outer housing body surrounding the piston. The housing has a stop surface selectively in contact with the forward end of the radially outer stop portion of the piston to block flow for a housing inlet to a housing outlet. The radially inner sliding portion slides on a support tube. At least a portion of the radially inner sliding portion is formed of a first material having better wear resistance than a second material forming the outer stop portion of the piston. The second material has a greater resistance to high temperature and pressure than the first material. A vent valve for a compressor is also disclosed.
