Abstract

989,225. Valves. D. HAUBOLD. July 31, 1961 [July 29, 1960], No. 27749/61. Heading F2V. The supply and exhaust of air to and from the operating piston of a machine e.g. a stapler, is controlled by venting the chamber beneath the piston 51, Fig. 2, of a valve 47 upon lifting an operating lever so unseating an auxiliary valve 68 and preventing further admission of air thereto from the supply passage 48 by urging the upper end of the rod 45 on to a seat 64. The pressure in the supply passage 48 is then enabled to open the valve 47 and admit air to the working port 65; subsequently the valve 47 closes the exhaust passage 67. -Upon releasing the operating lever the rod 45 falls to the position shown so that supply pressure acts on the piston 51 to seat the valve 47 and open the port 65 to the exhaust passage 67. The main valve may be formed as a lift closure by an " 0 "-ring in a groove on the main valve stem whilst the auxiliary vent valve has plane sealing surfaces. In a modification, a pin 103, Fig. 4, is elevated either directly or by the operating lever to unseat a spring-loaded ball-valve 93 and allow air from the supply passage 81 to enter a chamber beneath the piston 84 of the main lift valve 77 so opening the passage 81 to the working port 105 and causing the piston 84 to block the exhaust passage 106. Upon releasing the pin 103 the ball valve 93 is spring closed and the supply pressure closes the main valve 77.
