Abstract

989,920. Valves. BOHLER & CO., A.G. GEB. July 12, 1963 [July 12, 1962], No. 27671/63. Heading F2V. A valve is operated by a longitudinally movable stem 3, 4 moved by a reversible compressed air motor 26, the flow to and from this motor taking place past respective annular grooves 10, 11 in two pistons 5, 6 which control ports 15, 16 and 17, 18 respectively in a cylinder 2. The pistons are urged apart against stops by a spring 7 and are engageable by respective abutments 25, 8 on the stem 3, 4 whereby as the stem approaches a limiting position in either direction the return flow from the air motor is throttled by one or other of the pistons and the stem is gradually arrested in its limiting position. The device is controlled by a reversing valve connected to the ports 16, 17, the other ports 15, 18 being connected to the motor which drives the stem through gearing 28, 27 and a sleeve 1 threadedly engaging the stem. The valve may be operated manu ally by hand wheel 32 upon withdrawal of a shaft 29, the motor being disengaged by a coupling 30.
