Abstract:
A piston machine comprising a piston disposed in a cylinder, a working chamber formed by the piston and the cylinder, a pump comprising at least one pump chamber connected to the cylinder, the cylinder comprising plural injection ports including a first injection port and a second injection port, the second injection port disposed in a wall of the cylinder, a receiver connected to the pump chamber by the second injection port, said piston machine having only one piston in every cylinder, a suction valve on the piston machine, a supply system for supplying charges to the piston machine wherein the piston by reciprocation sucks in the charges, wherein at least one of the charges is a supplementary aftercharge to the charges supplied at the suction valve, the supply system being coupled to the working chamber of the piston, the charges being supplied by being blown through said first injection port on the wall of the cylinder, the first injection port being positioned proximal to a position of a piston top of the piston when the piston is at a bottom dead point and at said position the first injection port is completely exposed by the piston top, an exhaust duct, an annular duct connecting the plural injection ports and the exhaust duct to a dead volume of the pump for compressing and minimizing the supplementary aftercharge, the receiver being coupled to the exhaust duct, a differential pressure controlled check valve disposed in the exhaust duct proximal the dead volume of the pump, wherein the receiver comprises a device for adjusting a volume of the receiver such that an individual volume of the receiver is increased or reduced by adjustment of the device.
