Abstract
A piston pump for conveying a fluid includes a cylinder which is not flanged to the pump casing, but rather is inserted in the pump casing and is retained in the longitudinal direction by a pretensioned spring. A seal is arranged between the cylinder jacket and the pump casing in order to seal the pressure side with respect to the suction side of the piston pump. An extremely compact piston pump results therefrom, suitable, in particular, for use in the low-temperature range due to very low cold losses.
