Abstract:
A pump (20) for pumping fluid, wherein the pump (20)comprises a working chamber (200), a piston assembly (202) configured for reciprocating within the working chamber (200) to thereby displace fluid, a piston actuator (204) being rigidly assembled with the piston assembly (202) at least in a working mode of the pump (20) to thereby transmit drive energy to the piston assembly (202) to reciprocate along a common rigid axis (206) of the piston-actuator-assembly, and a bearing arrangement (208, 210) bearing the piston assembly (202) and the piston actuator (204) in the pump (20) so that the piston-actuator-assembly provided by the piston assembly (202) and the piston actuator (204)is capable of performing a pendulum-type compensation motion around a pendulum point (212) at the piston actuator (204) on the common rigid axis (206).
