A hydraulic door closer capable of reducing oil-pressure therein at high temperature, comprises a housing with an oil chamber, an oil storage cavity, and a piston in the housing of the hydraulic door closer. The oil storage cavity is in communication with the oil chamber; when the oil temperature increases, hydraulic oil in the oil chamber and oil storage cavity generates an increased oil pressure move the piston, whereby volume of the oil storage cavity is enlarged, such that oil from the chamber will flow into the cavity, to reduce the oil pressure of the chamber and cavity. When the oil temperature decreases, the oil pressure in the chamber and cavity is reduced, whereby the storage piston restores its original position, whereby volume of the cavity will be reduced, and the oil in the cavity flows back into the chamber. The pressure in the oil chamber is reduced when the hydraulic oil expands due to increased temperature to prevent failure of the seal and to avoid hydraulic oil leakage.

A closing aid for a luggage compartment flap is described, which closing aid comprises an actuating element, a movement element and a connecting element. The actuating element is integrated in a locking mechanism of the luggage compartment flap. The connecting element connects the actuating element to the movement element and transmits a movement of the actuating element to the movement element such that the luggage compartment flap fastened to the movement element is moved at least part of the way from an open position to a closed position. A luggage compartment and a vehicle having a closing aid of this type are also described.
