Abstract
In this piston pump, the pump housing (1) is provided with a mounting (E) for a vessel (3), which consists of a pipe end (4) provided with a hollow needle (5) and of a connecting element (9, 16, 17) for connecting the vessel (3) to the pipe end (4). The pump housing (1) has an inlet channel (7) which is connected to a channel (6) in the pipe end (4). So that the vessels (3) can be connected rigidly to the piston pump, the connecting element consists, for example, of a metal sheet (9) bent in the form of a U, which is provided on its inner side with U-shaped yokes (10, 11), the yoke (10) facing the pump housing (9) engaging into a groove (12) provided in the pipe end (4) and the other yoke (11) serving for surrounding the vessel neck.
