Abstract
There is disclosed a reset mechanism particularly adapted for use within a magnet valve in which the reset mechanism comprises a passageway within the valve housing connecting the inlet and outlet passages in which a reset valve normally interrupts a communication between the inlet and outlet side of the said reset passage to permit normal operation of the magnetic valve and to permit normal fluid flow through the inlet and outlet passages thereof prior to movement of said magnetic valve from its normally open to its normally closed position. After said magnetic valve has closed, this being responsive to a pre-determined excess of fluid pressure across the primary communication area between the inlet and outlet passages of the magnetic valve, the reset valve can be actuated to open the reset passage thereby creating an equalization of pressure between the outlet and inlet ports, thus eliminating the existence of any relative vacuum across the area of primary communication between the inlet and outlet passages and, thereby, eliminating any opposition to the return of the magnetic valve to its normally open position.
