Pressure regulator

Pressure regulator for a gas-heated heating appliance with a fan (21) which is connected via chokes to an air inlet and a gas inlet and whose pressure side is connected to a burner, the outflow side of an air orifice (20) being connected to a space (43) of the pressure regulator (29) defined by a co...

Zusammenfassung:	Pressure regulator for a gas-heated heating appliance with a fan (21) which is connected via chokes to an air inlet and a gas inlet and whose pressure side is connected to a burner, the outflow side of an air orifice (20) being connected to a space (43) of the pressure regulator (29) defined by a control diaphragm (10) and a servo diaphragm (11), and a space (45) defined by the control diaphragm (10) being acted upon by the pressure in the low-pressure chamber, and the servo diaphragm (11) controlling a valve (12) which influences the inflow to a space (41) defined by a regulating diaphragm (8) which controls a gas-regulating valve (5). In order to ensure a constant regulator pressure pR, provision is made for a holding part (15) with an internal thread (49) to be pressed into one of the two diaphragms (10, 11) defining a space (43). Adjustably held in the holding part (15) is a screw (14) which determines the distance between the two diaphragms (10, 11).
