SOLENOID VALVE ASSEMBLY WITH PILOT PRESSURE CONTROL

A valve assembly includes a valve body with an interior cavity and one or more supply ports, a control port, and an exhaust port each fluidly connected to the interior cavity. An armature assembly ismovable within the interior cavity from a first position to a second position in response to the coil being energized. In some configurations, a regulator body, which is connected to the valve body, has an exhaust passage fluidly connected to the exhaust port. A regulator valve in the regulator body prevents fluid flow out of the exhaust passage when fluid pressure on the regulator valve is at orbelow a pilot pressure. The regulator valve permits fluid flow out of the exhaust passage when fluid pressure on the regulator valve is greater than the pilot pressure. The valve body is configured toprovide fluid from the supply port/ports to the control port. 本发明公开了一种阀组件，该阀组件包括阀主体，该阀主体具有内部腔体以及一个或多个供应端口、控制端口和排出端口，这些端口各自流体地连接到内部腔体。电枢组件能够响应于线圈被通电而在内部腔体内从第一位置移动到第二位置。在一些构型中，连接到阀主体的调节器主体具有排出通道，该排出通道流体地连接到排出端口。当调节器阀上的流体压力在先导压力下
