<p>The invention relates to a changeover valve (10), comprising a valve housing (3), which has at least two fluid openings (4, 5, 6), of which a first fluid opening (4) is provided in an opening plane arranged transversely to the longitudinal extension of the housing and at least one further fluid opening (5, 6) is provided on the housing circumference, and comprising a valve body (7), which is connected to an actuating element by means of valve tappet (8) movably guided in the longitudinal direction of the housing. At the actuating element, the valve body (7) can be moved against a restoring force from a first actuating position that closes the first fluid opening (4) to a second actuating position that opens the first fluid opening (4). The changeover valve (10) according to the invention is characterized in that at least one tension element (16), which can be extended in the longitudinal direction and which is made of elastic material, is provided as a restoring force. The tension element is retained on one side on the valve body (7) and/or on the valve tappet (8) and on the other side on the valve housing (3). The tension element (16) provided in the changeover valve (10) according to the invention makes a restoring spring dispensable and can optionally be made from the same elastic material from which the seals provided in the housing interior and/or on the valve body (7) are made.</p> |
