Abstract

1,055,684. Valves. HOERBIGER VENTILWERKE. July 23, 1965 [Aug. 14, 1964], No. 31435/65. Heading F2V. In a compressor check valve, Fig. 1 (not shown), a valve member 6 is movable between a valve plate 1 and a guard 2. The valve member is loaded and guided by a helical spring 7 which rests radially at opposite ends against cylindrical surfaces 9, 10 provided respectively on the guard and on the valve member. To reduce shock and wear by ensuring even seating, at least one end of the spring, where it rests radially has a machined finish so that it fits closely. In a modification, a radially outer surface of the end coil engages an inwardly facing surface on the valve, member. In another modification, a round wire spring is used.
