Inline piston pump

Abstract

The present invention relates to an inline piston pump, comprising a driveshaft for driving the inline piston pump; at least two pistons which are operatively connected to the driveshaft and are disposed along a driveshaft axis and are in each case disposed so as to be movable in a reciprocating manner in a piston chamber; a suction connector for supplying a fluid to be pumped; wherein a suction valve is disposed in at least one, preferably in each, piston chamber in order to fluidically separate a suction duct for the inflow of fluid from the piston chamber during a compression movement of the associated piston. The pump is characterized in that a suction throttle valve which is conceived for varying a volumetric flow of a fluid to be pumped between the suction chamber and the suction duct is provided between the suction connector and the suction duct which in fluidic terms is connected directly to the at least one valve.
