Thermostatic valve

Thermostatic valve comprising:

• a thermostatic working element;
• an inflow valve arranged in an inflow;
• a bypass valve arranged in a bypass to a return flow,
• wherein said valve includes a preassembled constructional unit which can be inserted into a valve housing and which contains a thermostatic working element including a restoring spring, and movable valve elements,
• wherein the constructional unit has a holding part which can be inserted into the valve housing and in which a thermostatic working element housing is guided in an axially slidable manner which is provided with a valve element of the inflow valve and with a valve element of the bypass valve and, from its end facing away from the holding part, a working piston can be moved out, a support of the valve housing being situated opposite thereto, and
• wherein the holding part is fastened in the valve housing by means of securing devices which extend transversely to the insertion direction of the constructional unit and engage in recesses of the valve housing and of the holding part.

• wherein the thermostatic working element housing is provided with a collar which forms a valve slide for the inflow valve and which is inserted into the chamber of the valve housing into which the inlet and the outlet of the inflow lead which are axially offset with respect to one another, and
• wherein the pin reaches by means of a flanged-open edge behind an end of the guide bore of the holding part.
