Abstract

759,235. Piston and cylinder mechanism for gear changing. SOC. ANON. A. SAURER. Nov. 16, 1954 [Feb. 27, 1954], No. 33135/54. Class 80(2) A power device, particularly for gear changing in motor vehicles, comprises a piston 5 capable of assuming three positions in its cylinder 1. Rings 7, 8, with packing 9, 10, are located between the piston perimeter and cylinder bore. Stop rings 12, 13, are fixed to the ends of the piston and stop rings 14, 15, are fixed to the cylinder ends. The cylinder has three ports 2, 3, 4, for the admission of pressure fluid. Fluid pressure admitted through port 2 or port 4 will move the piston to one or other end of the cylinder, whereas fluid pressure admitted through port 3 will locate the piston in a central position due to the cooperation of the stops 12...15 with the rings 7, 8.
