Abstract (en)
[origin: WO9737162A1] A boost-enhanced gas pressure regulator (53) consists of a bonnet (11) and a body (12; main casing) that are secured together so as to capture a diaphragm (13) between both components. An actuator (16) providing a pair of control channels (38) and a relief seat (32) in one component is connected to the diaphragm (13) to be moved with and by the latter. A boost/seat tube (20) has external guide surfaces (49) which serve to guide and control its movement, and it also has an internal gas flow passage (52) in which an elastomeric seat disk (21; valve member) is mounted. The boost/seat tube (20) is restricted to travel in a linear fashion (direct action) with respect to an inlet orifice/valve seat (44) by a plurality of guide surfaces (49) that are an integral part of the orifice insert (44), upon which certain contact areas (70, 72) of the boost/seat tube (20) are slidable.
