Abstract

532,977. Reciprocating pumps for liquids. COCHRANE, W. Sept. 26, 1939, Nos. 26690/39 and 6251/40. [Class 102 (i)] [Also in Group XXVII] A multiported disc valve 1 for internalcombustion engines and pumps is oscillated in one direction to bring ports 2 into line with exhaust ports in the cylinder head, and in the other direction with inlet ports, and is held stationary with the ports closed during an intermediate period, as in compression and firing. The valve is held against its seat, and also brought back to the central position, with the ports closed, by springs 13, 14 connected to an arm 7 which carries a roller 8 engaging a grooved cam 9. The valve may be lifted from its seat during the oscillating movements, by another cam 19 which acts on the top of the valve stem 6 through a lever. Air or mixture is admitted through a chamber 25, and exhaust takes place through a chamber 27. The spark-plug, where this is used, may be placed at 33 in line with a passage 34, which communicates with one of the valve ports 2 during the stationary period. A fuel-injection pump may be operated by a cam 35. The valve may be formed with central and peripheral ribs 15, 17 to assist fluid tightness. In a two-stroke engine, the valve may control exhaust ports only. Air due to the movement of the aircraft or vehicle may enter at 26 into the chamber 25 so as to have a cooling effect and may flow therefrom through a pipe adjacent the exhaust outlet.
