ABSTRACT:
A fluid flow sensing switch device having a housing provided with a fluid flow passage therethrough defined by an inlet and an outlet disposed in spaced coaxially aligned relation in the housing and separated by a valve seat controlled by a movable valve member that is operated by the pressure differential between the inlet and the outlet, the device having an electrical switch construction operatively associated with the valve member and having the switch contacts thereof actuated by the pressure differential. A pressure regulator is disposed in the housing for regulating the pressure of the fluid that passes from the inlet to the outlet of the housing, the pressure regulator being disposed downstream from the main valve seat so as to act on the fluid after the same passes through the main valve seat from the inlet. The pressure regulator has a valve seat and a valve member for controlling the valve seat thereof, the valve seat of the pressure regulator and the main valve seat being disposed in spaced coaxially aligned relation in the housing and substantially transverse to the coaxially aligned inlet and outlet.
