摘要:
A pressure control valve having a housing with a main inlet passage and a bypass outlet passage. A combined control is located in the housing to control the flow of fluid from the main inlet passage to the bypass outlet passage. The combined control includes a chamber in the housing having an inlet connected to the main inlet passage, an outlet connected to the bypass outlet opening and a loading opening. A poppet is located in the chamber and is movable between a first position closing the inlet and a second position opening the inlet to allow fluid to flow from the main inlet passage to the bypass outlet passage. A spool is positioned within the poppet and is movable between an open position allowing fluid to flow between the main inlet passage and the bypass outlet passage. A spring biases the spool toward the closed position. A connecting passage is located in the housing to connect the main inlet passage to the loading opening.
