摘要：A microvalve device for controlling fluid flow in a fluid circuit. The microvalvedevice comprises a body having a cavity formed therein. The body further has first andsecond pilot ports placed in fluid communication with the cavity. The body also has firstand second primary ports placed in fluid communication with the cavity. Each port isadapted for connection with a designated fluid source. A pilot valve supported by thebody is movably disposed in the cavity for opening and closing the first and second pilotports. An actuator is operably coupled to the pilot valve for moving the pilot valve. Amicrovalve is positioned by the fluid controlled by the pilot valve. The microvalve is aslider valve having a first end and a second end. The slider valve is movably disposed inthe cavity for movement between a first position and a second position. The first end ofthe slider valve is in fluid communication with the first and second pilot ports when thefirst and second pilot ports are open. The second end of the slider valve is in constantfluid communication with the first primary port. When moving between the first andsecond positions, the slider valve at least partially blocks and unblocks the secondprimary port for the purpose of variably restricting fluid flow between the primary ports.
