Abstract
859,543. Engine turning gear. UNITED AIRCRAFT CORPORATION. Aug. 26, 1958 [Sept. 3, 1957], No. 27317/58. Class 7(5). [Also in Group XXXIII] Apparatus for starting an internal-combustion engine 152 normally driving a hydraulic pump 150 through a shaft 151 is shown. A two-way valve 184 has a rotatable member 192 with two passageways 202, 204 co-operating with ports 194, 196, 198, 200. Port 194 is connected through non-return valve 208 to the pump outlet 154, port 196 to an accumulator 180, port 198 to the pump inlet 162, and port 200 to a reservoir 182. Normally the valve is in the position shown, so that the pump pressurizes accumulator 180 through non-return valve 208, and the inlet 162 is connected to the reservoir. To start engine 152, the valve is changed over, so that the accumulator is connected through ports 196, 198 to the pump inlet 162, and the outlet is connected through ports 194, 200 to the reservoir. The pump is thus driven by the pressure fluid from accumulator 180 to turn over the engine. A hand pump 220 is provided to pressurize the accumulator 180 at any time.
