Abstract

699,233. Vacuum motors; engine valve gear. O'SHEI, W. E. Nov. 8, 1950 [No. 8, 1949], No. 28544/49. Classes 110(ii), 122(ii) and 122(iii) A suction motor with a vane 2, in a chamber 1, and " snap-over " valve mechanism for supplying suction to either of ducts 19, 20 from a source 18, is provided with a stop member, such as a pin 25, which is positioned to prevent the valve 7 from snapping over. This allows suction, to act on one side only of the vane which is thus parked at one end of its stroke. The valve mechanism comprises the semi-rotary valve 7 movable over a valve face having three ports 8, 9, 10, to connect with ducts 19, 18, 20 respectively, the valve snap action being effected by a " kicker " 11 which is moved through engagement with radial surfaces 12 on the end of the vane shaft 3. A stirrup 13 is connected by a spring 14 to a pressure plate 15, pivoted at its bottom end, the plate causing light pressure to hold the valve 7 against its valve face. The spring also secures the "snap-over" action when the kicker 11 engages one of the ears 7a of the valve. A knob 29 is used to push in the stop pin 25. Remote control means, which may be mechanical or electrical, may be used to move the stop pin, and more than one pin may be used. Flexible sealing members 23, 24 coact with valve faces 21, 22. Frictional means may be used to stop the valve movement. A guard plate 30 prevents the insertion of the pin 25 when the kicker is in its right-hand position, Fig. 1. Specifications 546,483, 557,377, 557,696 are referred to.
