PUMP UNIT FOR A POWER TAKE-OFF, POWER TAKE-OFF FOR A TAKE-OFF MODULE, TAKE-OFF UNIT AND A VEHICLE INCLUDING A POWER TAKE-OFF

摘要

The invention pertains to a pump device (22) for a power take-off (16) in a vehicle (1), comprising a fluid inlet (32); a fluid outlet (34); a rotor (40), connected to the fluid inlet (32) and the fluid outlet (34), which is arranged on a drive element (20); a stator (42), interacting with the rotor (40) and arranged inside a house (18). A shiftable and reconfigurable switching element (54), which in a first state interacts with the rotor (40) and the stator (42), so that substantially no fluid flow is generated by the pump device (22), and in a second state abuts against the stator (42) and the rotor (40), so that a fluid flow is generated through the pump device (22). The invention also pertains to a power take-off (16) for a take-off module (14), a take-off module (14) and a vehicle (1), comprising a power take-off (16).
