Abstract
177,754. Bunker, W. H. Oct. 20,1920. Valve gear and valve-actuating arrangements; pump - actuating mechanism.-A compressor, particularly intended for use with the rotary engine-described in Specification 174,689, comprises a compressor cylinder and a reservoir cylinder, the compression cylinder having an air port at each end controlled by a slide valve, the two valves being connected by a lever, and a cam mechanism operating against the opposite ends of each valve, the piston of the reservoir cylinder at the end of each stroke tripping one of these mechanisms to close the corresponding valve and open that at the other end. The ends of the two cylinders are connected by valved pipes, and the reservoir cylinder is provided with a valved discharge pipe. The apparatus shown comprises a compression cylinder 81, Fig. 1, and a reservoir cylinder 82, each with a piston, the rod 85 of the compressor piston being driven through a link 9U, Fig. 7, slotted lever 87, sliding rod 93, pitman 103, and toothed gear from pinion 8 on the engine shaft. Reciprocation of the compressor piston draws gas in by a valved pipe 105, Fig. 1, and forces it into the reservoir cylinder through a valved pipe 107, the reservoir piston being gradually forced in the direction shown and carrying with it a slide bar 115 and a cam bar 118 against which a pivoted swinging arm 120 rests. When the reservoir is full of gas and its piston has accordingly reached the end of its stroke, the inclined end 119 of the cam-bar 118 releases the arm 120, allowing its lower end to swing into the path of a projection 132, Fig. 3, on the compressor piston-rod 85. The stroke of this rod carries the projection against the portion 131 of the arm carried by a spring-held extension 126, and forces it against a lever 133, which is thus caused to draw a slide bar 135 outwards. A wedge 140 on this bar depresses one end of a lever 141 against spring pressure and thereby causes the lever to release a sector I44, Figs. 1 and 3, which is thereupon swung downwards by a spring 191, and causes a cam rib 195 on its face to lift a bar 173 carrying an orifice 175 out of line with an orifice 177 in the end of the compressor cylinder. A lever 181 connects the bar 173 with a like valve-bar 174 which is thus depressed till its orifice comes into line with an orifice 180 in the other end of the cylinder. The gas inlet end of the compressor is thus opened to atmosphere, and opening of the gas inlet valve prevented. The further action of the compressor draws air in by a valved pipe 207, Fig. 1, and forces it into the reservoir, driving the reservoir piston back until the gas is under a certain pressure determined by a controlling-valve 216 which opens at any excess above this pressure. As the reservoir piston is carried back by the inlet of air and the comsumption of the gas, the slide bar 115 moves with it bringing a swinging arm 213 against a pin on the sector and forces it back. At the end of its travel, the bar carries a wedge 157 beneath one end of a transverse lever 152, forcing a rod 151 down and driving a wedge on the rod between a lever 145 and a plug which is thrust inwards through the compressor cylinder end. The motion of the compressor piston forces the plug and the lever 145 outwards, bringing a wedge 164, Fig. 3, on a bar 146 into contact with a spring-pressed lever controlling a sector, and releasing this sector so that a cam rib 196 forces the valve bar 174 upwards and consequently forces the bar 173 downwards. The compressor may then again draw gas and force it into the reservoir.
