ABSTRACT:
A gas regulation device to delay for a predetermined time the closing of a gas actuated main valve of the type having a main valve conduit connected to the main valve for carrying the gas which actuates the main valve. The regulation device comprises a first conduit which can be disposed in the main valve conduit to form a portion thereof and a check valve which is disposed in the first conduit so that gas can pass through the first conduit only in one direction. A bypass conduit is connected to the first conduit across the check valve such that gas can pass from the first conduit on one side of the check valve through the bypass conduit to the first conduit on the other side of the check valve. A flow regulation device is disposed in the bypass conduit to limit the flow of gas through said bypass conduit such that the pressure drop or increase required to open or close the main valve is delayed for a predetermined time.
