Abstract
A pressure regulator for independent automobile heater fuel lines, particularly for connection upstream of a dosing pump. The pressure regulator includes an upper housing portion, and a lower housing portion which are connected together with a diaphragm being disposed between the upper housing portion and the lower housing portion. The diaphragm operates with the upper housing portion to form an air space and cooperates with the lower housing portion to define a pressure regulation space. An adjusting lever is positioned within the pressure regulation space attached to an adjusting piece which in turn is attached to the diaphragm. An inlet is provided opening into the pressure regulation space and an outlet is provided leading to a dosing pump or the like. A control member is positioned within the inlet having a sealing ring about it. The control member has a cylindrical shaft portion which is slightly smaller than a boring in the inlet connection. The cone-shaped pressure piece is positioned at the end of the control body contacting the lever. The movement of the lever causes the restriction of the inlet in response to movement of the diaphragm.
