A fill device for filling a system, via a fill pipe thereof, with a liquid to a selected fill level, which device includes a housing, a rod axially displaceably mounted in the housing with one end of the rod forming a liquid outlet opening arranged to extend into the fill pipe to the selected level, a flow control unit connected between the outlet opening and connections for liquid supply and extraction lines and operable to connect a selected one of those lines to the outlet opening, a clamping mechanism mounted in the region of the outlet opening and operable to clamp the device onto the fill pipe, and an operating member operatively associated with the rod, the flow control unit and the clamping mechanism for causing displacement of the rod relative to the housing to simultaneously control operation of the flow control unit and the clamping mechanism.
The two end members (1, 4) are locked by a self-retractable hook (15) which engages in a groove (23) in the female end member (1). The hook (15) is connected to an actuating lever (11) biased by a spring (14) and provided with a push-button (20). Pivotally mounted on the other arm of the lever (11) is a yoke (6) mounted on the male end member (4). When the transfer has finished, the hook (15) is retracted by depressing the button (20) so as to unlock the coupling. In the event of frosting, by depressing the button (20) still further, the yoke (6) upwardly urges the female member (1) and separates the two end members. Application in the transfer of liquid oxygen from a storage container to a portable container for domestic oxygen treatment.
An apparatus for adding coolant to a cooling system of a motor vehicle includes a cap with a resilient sleeve that expands against the inside wall of a radiator filler neck to provide an air-tight connection. A valve attached to the cap controls the flow of air and coolant through the cap. A gauge on the cap indicates the pressure inside the radiator. A venturi assembly connected to the valve provides a source of vacuum for evacuating air from the cooling system. Thereafter, coolant is drawn through the cap by the vacuum created in the system.

The device (102) is intended to inject a gas under pressure into an aerosol receptacle (100) through a pump or spray head crimped onto said receptacle. The purpose of the gas is to prevent air from penetrating into the aerosol receptacle as the liquid contained therein is sprayed out. The device is actuated by the pressure of the filling gas and it includes a damping system for ensuring uniform operation.
