Mixing valve

A mixing valve comprising a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force against the resetting force of at least one spring, wherein one of the at least one spring is realized as a recoil spring and one of the at least one spring is realized as a regulator spring, wherein the recoil spring comprises less rigidity than the regulator spring, and wherein the at least one spring are realized in such a manner that a force acting in opposition to the spring forces of the at least one spring initially compresses exclusively the recoil spring and only subsequently or in part simultaneously compresses the regulator spring.

A mixing valve comprising a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force against the resetting force of at least one spring, wherein a monolithic contact piece comprises a guide surface for the one valve body part and/or a stop surface for the other valve body part.

A mixing valve comprising a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force against the resetting force of at least one spring, wherein a monolithic contact piece defines a ring gap at least in regions.

A mixing valve comprising a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force against the resetting force of at least one spring, wherein a monolithic contact piece comprises a guide surface for the one valve body part and/or a stop surface for the other valve body part, and wherein the monolithic contact piece comprises a support surface for a recoil spring, which support surface is located remotely from the other valve body part.

A mixing valve comprising a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force against the resetting force of at least one spring, wherein a monolithic contact piece comprises a guide surface for the one valve body part and/or a stop surface for the other valve body part, wherein the monolithic contact piece comprises a support surface for a recoil spring, which support surface is located remotely from the other valve body part, and wherein the recoil spring is arranged in a ring gap of the monolithic contact piece.

A mixing valve comprising a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force against the resetting force of at least one spring, wherein the valve body part facing the switching valve comprises on its one end at least one cleaning continuation which is realized and/or arranged in such a manner that it can come into contact with a surface of the valve body part facing the proportional valve part, which surface is located opposite the at least one cleaning continuation.
