Abstract
A pump, particularly a vane-type pump, including a rotor guiding at least one vane and resting against at least one pressure plate, which has at least one pressure through-hole and at least one under-vane through-hole, the holes being connected to a pressure outlet provided in a housing of the pump or in a transmission housing. In between the pressure plate and the housing a flow guide device is arranged, which delimits a fluid path from the pressure through-hole past the under-vane through-hole to the pressure outlet.
