Abstract: 883,258. Two-stroke supercharged engines. BROWN, ROVERI & CIE A.G. May 14, 1959 [May 24, 1958], No. 16567/59. Classes 7(2). and 7(6). In a two-stroke engine supercharged by an exhaust-driven turbo-supercharger 13, Fig. 1, in series with a plurality of piston pump superchargers 16, the delivery of the piston pumps is reduced at maximum speed by connecting together the compression spaces of at least two of the pumps operating out of phase. In Fig. 1 the delivery of the piston pumps 16 is controlled by interconnecting the pump chambers of one or more pairs of pumps operating at different crank angles through a valve 21 which is open at maximum speed and is closed as engine speed decreases. In a modification, Fig. 3, in addition to control by the interconnecting valve 21 the inlet of one piston pump 16<SP>1</SP> may be disconnected from the receiver 15 of the turbocharger 14 by a valve 30 and opened to atmosphere to reduce the pump delivery. In Fig. 4 a rotary supercharger 31 driven by an electric motor 32 is provided in addition to the piston pumps 16. As engine speed decreases, the pump delivery is increased first by control of the interconnecting valve 21 and secondly by switching on the blower 31. The scavenging-pressure may be arranged to decrease slightly over the predetermined speed range to enable the pump delivery to be controlled by this varying pressure.
