Abstract
18,430. Tygard, F. C. Aug. 7. Four-stroke- and twostroke-cycle engines.- Part of the charge compressed in the working cylinder escapes through a port controlled by a rotary valve, and is admitted to the same or to another cylinder and fired on the next downstroke. The exploded gases expand to atmospheric pressure during the working strokes. Fig. 1 shows an engine with cylinders 1, 3 working on a four - stroke cycle and firing alternately, the rejected portions of the compressed charge from each cylinder being used in the central cylinder 2, which thus gives an impulse at every revolution. In a single - cylinder engine, the rejected portion of the compressed charge is stored in the rotary valve and readmitted after the exhaust stroke, the engine thus working with a four-stroke cycle followed by a two-stroke cycle. The rotary valve 24, Fig. 1, for controlling the distribution is divided into two similar parts by a partition 38, and each part of the valve has an inlet port such as 39 for the cylinder 1 or 3, ports such as 43, 45 for the transfer of the compressed charge to cylinder 2, and recesses 42, 44, and two others (not shown) forming the exhaust ports. The valve is rotated at half the speed of the crank-shaft by a chain running over adjustable jockey-wheels such as 58, by means of which the timing of the valve can be varied. The valve is driven through a jaw clutch 31, which is kept in engagement by a spring 35. Reference has been directed by the Comptroller to Specification 15,472/86.
