ABSTRACT:
A pressure switching valve device including: a valve adapted to open and close an orifice defined in a valve seat; a diaphragm cooperating with the valve and so loaded as to maintain the valve in its open or closed position; and an atmospheric density compensating mechanism in engagement with the diaphragm to compensate for the opening and closing operations of the valve in response to the variation in atmospheric density, whereby the valve is opened and closed by impressing a given pressure on the diaphragm. This valve device features that the direction of a force exerted on the diaphragm so as to maintain the valve in its normally open or closed position is in coincidence with the direction of a force exerted by the atmospheric density compensating mechanism.
