    摘要: The invention relates to a pressure regulator for a fuel supply unit on a motor vehicle, whereby a membrane (11) is connected to an annular element (3) of the housing (1) and a moving piston (2) by a laser welding technique. A reliable sealing of the membrane (11) is thus guaranteed even at temperatures below 0° C. The region above the piston (2) is thus reliably separated from the region below the piston (2).
