This patent describes a fuel pressure regulator for internal combustion of automobiles and the like. It comprises a body including first, second and third chambers; a resilient impervious diaphragm separating the second and third chambers; a fuel inlet communicating with the first chamber; a fuel outlet communicating with the second chamber; a passageway for permitting fluid communication between the first and second chambers; a ball valve means adjacent one end of the passageway ball valve means comprising a movable ball and a movable valve seat; first biasing means for biasing the ball valve means at one end of the passageway; actuating means for actuating the ball valve means at the one end of the passageway, the actuating comprising a piston positioned in the second chamber in abutment with one side of the resilient impervious diaphragm and a stem extending from the piston with its distal end adapted to bear against the ball of the valve means; second biasing means in the third chamber in abutment with the other side of the resilient impervious diaphragm for biasing the resilient diaphragm to move the piston toward the first chamber; stem guide means positioned between the first and second chambers along the length of the stem and intermediate the ends of the stem for guiding the stem to limit the motion of the stem to a substantially linear, reciprocating motion while in contact with the ball of the ball valve means.
