<p>A pressure regulating solenoid valve is disclosed which comprises a valve body having a flow path therethrough having an inlet and an outlet. The valve body has a main valve seat within the flow path, and a main valve member mounted within the valve body for movement between an open position, in which the main valve member is clear of the main valve seat for the primary flow of fluid between the inlet and outlet, and a closed position in which the main valve member engages the main valve seat so as to block the primary flow of fluid through the main valve seat. A spring biased combination throttling valve/check valve is interposed within the flow path between the upstream and downstream sides of the main valve seat so as to permit a secondary flow of fluid from the inlet to the outlet of the valve housing when the main valve is closed and when the pressure differential of the flow through this secondary valve seat is above a predetermined value.</p> |
