Abstract

115,919. Fleuss, H. A. June 5, 1917. Compound piston pumps; valves, arrangement of.-In piston pumps for exhausting air and gases and of the kind in which the cylinder cover forms or contains centrally the delivery valve, with the under surface of which the top of the piston is coned to correspond, and a ram &c. supplies oil to the cylinder, the mechanism for actuating the ram is enclosed in a casing exhausted by a second pump, and the oil is supplied to the cylinder through a spring-controlled valve at the side of the cylinder close to the underside of the delivery valve. As shown, the pump comprises a cylinder a and a piston b with a conical recess b' to correspond with the cover c, which forms the delivery valve and is not reached by the piston. A casing o is exhausted through a pipe q by a second pump, and stuffing-boxes c<1>, d are provided in the cover c and the casing for the piston-rods b<2>. Oil is poured into the casing and fills a cylinder h, whence it enters a cylinder g<2> by ports g<4> and is forced through a pipe j to the cylinder a by a ram g<1>, the stem g of which is depressed against the action of a spring g<3> by a bell-crank lever f actuated by a slide c on the piston-rod b<2>. The pipe j contains a check valve k, and the oil enters the cylinder a near the valve c past a spring-controlled valve at l after the inlet ports n have been covered by the rising piston. To prevent an air or oil pocket from being formed at the bottom of the cylinder a, a slot m extends from one of the inlet ports n to the base of the cylinder, or the piston may be valved. The oil issuing from the cylinder returns through the casing to the ram.
