Filed: 1949-12-29
Abstract: 673,718. Liquid-pressure engines; spray-producers. SCOTT, H. E. B. Oct. 31, 1950 [Dec. 29, 1949], No. 33230/49. Classes 69 (ii) and 69 (iii). In a reciprocating hydraulic motor comprising a casing 10-14 having an inlet 35 for pressure liquid and an outlet 47, a pressure sensitive actuator 23 mounted to reciprocate in the casing, and a pilot valve 26 surrounded by a sleeve valve 36 mounted for reciprocation thereon between two alternative controlling positions, the sleeve valve establishes a hydraulic pressure difference across the actuator which is reversed in direction as the sleeve valve moves from one controlling position to the other and the pilot valve establishes a hydraulic pressure difference across the sleeve valve which is periodically reversed in direction by relative movement of the sleeve valve and pilot valve to cause movement of the sleeve valve from one controlling position to the other, the actuator 23 being arranged, as it is reciprocated by the pressure difference across it, to impart relative movement to the sleeve valve and pilot valve. The pilot valve 26 coacts with ports in the sleeve valve 36 to establish alternative pressure and exhaust connections to the opposite ends thereof, and when relative movement between the sleeve valve and the pilot valve occurs, the pilot valve is effective to close the exhaust connection to the end of the sleeve valve which is connected to exhaust prior to opening of the pressure connection to that end of the sleeve valve. The actuator 23 is connected to a reciprocating pipe 29 in a shower pipe 20 of the type described in Specification 658,129. The actuator is constituted by a diaphragm 21 continuously subjected to the pressure of liquid from the inlet 35, and a diaphragm 22 of greater effective area which is alternately subjected to pressure and exhaust depending upon the position of the sleeve valve 36, pressure liquid being conveyed from the space 42 and pipe 41 to a central circumferential groove 38 in the sleeve valve. Flow of pressure liquid through the conduit 49 to and from the diaphragm 22 is controlled by a needle valve 50. The pilot valve 26 is connected to the crosshead of the actuator 23 by a fitting 25. The diaphragms are clamped to the crosshead 23 and in a second embodiment the pilot valve and the sleeve valve are disposed in the crosshead, the pilot valve being held against axial movement by a fitting on the casing, the sleeve valve being pushed to and fro by the crosshead. In further embodiments the diaphragms are replaced by pistons of either dissimilar or equal area.

Filed: 1927-12-08
Abstract: 310,094. Jennings, I. C. Dec. 8, 1927. Centrifugal Sprengel pumps; starting, facilitating.-To facilitate the starting of a pump of the type having an eccentric of double eccentric casing and a rotor with blades or vanes arranged one behind the other around the circumference thereof and extending transversely across the pump chamber and in which a liquid is used to develop the pumping action, a substantial portion of the liquid is removed when the pump is stopped and is gradually restored when the pump attains normal speed. The Figure shows a vacuum pump driven by a slowspeed synchronous motor M. The liquid is supplied to an inlet port chamber 27 continuously through an open valve V and a valve v to regulate the rate of flow into the pump. When the pump stops, liquid flows out through the drain pipe 25 as the valve 26 is no longer subjected to a difference of pressure on account of leakage in the pump, on restarting, the valve 26 is closed automatically by the vacuum produced, and the pump is filled with liquid to the necessary quantity, the liquid thereafter passing to the discharge ports.
