Abstract
In a sanitary outlet unit (1), it is provided that a contact surface (6) is formed on a valve element (4) which is adjustable between an open position and a closed position in a flow path (2), which contact surface (6), in the open position, covers a corresponding, stationary counterpart surface (7) and, in the closed position, frees said counterpart surface (7), such that the valve element (4) is automatically held in the open position by the pressure in the flow path and returns to the closed position in the event of a pressure drop (cf. FIG. 1).
Claims23
A sanitary outlet unit, comprising:
- a housing (3);
- a valve element (4) arranged in a flow path (2) in the housing (3), the valve element is switchable between an open position and a closed position, the closed position being arranged below the open position in a use position of the sanitary outlet unit;
- the valve element (4) has a contact surface (6) which, in the open position, bears on a counterpart surface (7) of the housing (3) and, in the closed position, is spaced apart from the counterpart surface (7), such that the counterpart surface (7) in the closed position is adapted to be wettable by water in the flow path (2);
- an impact surface (8) formed on the valve element (4) and, in the open position, the impact surface is adapted to be acted upon by a pressure prevailing in the flow path (2), such that the contact surface (6) is pressed against the counterpart surface (7);
- and
- an actuating element (13) that is accessible from outside the housing (3) and with which the valve element (4) is transferable from the closed position to the open position, and the flow path is limited to a greater extent in the closed position than in the open position.
A method for actuating a sanitary outlet unit (1), the method comprising:
- arranging a valve element (4) in a flow path (2) in a housing (3) of the sanitary outlet unit;
- transferring the valve element (4) from a closed position to an open position lying above the closed position;
- acting on the valve element (4), in the open position, by a pressure prevailing in the flow path (2), and pressing and holding a contact surface (6) of the valve element (4) against a counterpart surface (7) on the housing (3);
- and
- after a pressure drop in the flow path (2), the valve element (4) automatically falling to the closed position.
