    摘要： A high pressure pump of a common rail pump system includes a pump body having a cylinder with a piston bore and a piston reciprocally driven in the piston bore to pressurize fuel in the cylinder. The piston has an inner end located in the piston bore and an outer end outside the piston bore. A bellow having a first opening and a second opening is arranged between the piston and the pump body, wherein the piston extends through the first and second openings, wherein the bellow is connected to the pump body such that the first opening is sealed on the pump body and wherein the bellow is connected to the outer end of the piston such that the second opening is sealed on the piston. This arrangement prevents mixing of engine oil and fuel. The bellow may be connected to a drainage line via a one-way valve.

    摘要： A plug-in pump includes a cylinder and a pump housing, wherein the cylinder has a cavity in which a movable piston is accommodated, wherein a first end of the piston delimits a pump chamber, and a second end of the piston is connected to a drive device for the piston. An inlet valve is arranged in the cylinder, which inlet valve connects the pump chamber to a feed line for a first fluid, and an outlet valve connects the pump chamber to an outlet. The pump housing has a cavity that forms a first chamber connected to a feed line for the first fluid, and at least one second chamber which is separated from the first chamber and which is connected to a fluid system of a second fluid. The first chamber is fluidically sealed off with respect to the second chamber.
