The device incorporates a compressor (2) driven by a mains or battery-powered electric motor (3) to fill a pair of equalising containers (7,7') from a compressed-air line (5) via a non-return valve (4). The containers are connected to a delivery valve (8) which can supply a correlated valve and cartridge. A pressure control circuit (11) maintains a preset constant pressure in the container, and switches-out the motor automatically if a maximum pressure of e.g. 7 atmospheres is attained. |
