INVENTOR: FERDINAND HOCHSTRASSER INVENTION: CHANGE-OVER VALVE WITH AUTOMATIC RESETTING ABSTRACT OF THE DISCLOSURE Water supplied from a mixing faucet or combination set via an inflow chamber to a change-over valve effects by impact pressure that a double-sided valve member - as a result of an asymmetrical arrangement between a first valve seat and a second valve seat - moves to the first valve seat, thereby blocking the supply to a shower outlet. Therefore, the water is conducted via the second valve seat into a bath-tub outlet. By actuating a draw-button, the double-sided valve member is reversed in order to block the bath-tub outlet and release the shower outlet. Impact pressure now effects self-locking in this position. When the water is turned off and impact pressure no longer prevails, the two-sided valve member thereupon moves into an inoperative position by the force of two mutually counteracting springs. The conduit leading to the shower is automatically emptied by means of an annular gap remaining between the first valve seat and the double-sided valve member. It is thus precluded that bacteria can multiply or be reproduced in standing water. - 1 -
