PNEUMATICALLY ACTUATED HPC BLEED VALVE, WHICH IS CONTROLLED BY A SOLENOID VALVE, WHICH IN TURN IS ASSISTED IN ITS CLOSING POSITION BY A FLOW LIMITING VALVE

摘要

A bleed valve system includes a flow path (102) defined between a system inlet (104) and a system outlet (106). A pressure control mechanism (108) is defmed in the flow path downstream from the system inlet to selectively block fluid flow in the flow path. A pressure limiter (110) is defined in the flow path downstream from the system inlet (104) and upstream from the pressure control mechanism (108) to block the flow path when the pressure at the system inlet is greater than the pressure capacity of the pressure control mechanism (108).
