Abstract

The invention relates to a filling device for a reservoir which reservoir is to be filled from a cartridge such as cartridges having rigid walls e.g. made of glass and provided with a membrane which can be penetrated by a needle for protection of the entrance. According to the present invention the filling device comprises—a housing (1) which housing (1) comprises—a first position means adapted to receive a reservoir (2) for a delivering device,—a second position means adapted to receive a cartridge (3) containing a liquid,—a unit (4) providing a flow path when both the reservoir (2) and the cartridge are received respectively by the first and second positions means,—a venting unit (5, 5a, 5b) providing access of gas to the cartridge (3) during emptying of the cartridge (3). The filling device is characterized in that at least a part of the venting unit (5) is placed off the rotational centre (rc) of the housing and is attached to a part (7) which part (7) can rotate relative to the housing (1).
