301,092. Brouwer, G. Nov. 25, 1927, [Convention date]. Compound &c. engines ; engines with two or more parallel cylinders perpendicular to main shaft; tandem-cylinder engines.-An engine is provided with cylinders working on three cranks arranged at 120‹. There are two low-pressure, unidirectional-flow cylinders and one high-pressure, alternating-flow or, alternatively, high and intermediate counterflow single-acting cylinders arranged tandemwise act on one crank. Steam is supplied to the high-pressure cylinder 1 from an inlet 2 under the control of a piston valve 3 which controls the outlet to passages 6, 7, 8, 9 of the low pressure valve chamber 10, 11 which act as receivers. The admission to the low-pressure cylinders is controlled by valves 12, 13 which may also control an auxiliary exhaust. The valves 3, 12, 13 are of equal diameter. A modification is described wherein Van der Kerkhove piston valves are used. In a further modification, tandem single-acting, piston-valve controlled, high and intermediate pressure cylinders with a receiver between the pistons, operate on one crank. The low-pressure cylinders may have auxiliary outlet ports. The cylinders may be controlled by lift valves.
