The invention relates to a thermostat insert comprising at least one return spring, a thermostatic working element having a working piston that can be pushed out of a housing of the working element against the force of the return spring, a main valve element, and a short circuit valve element connected to the working element displaced when the working piston is pushed out of the housing, a base element in particular implemented as a base plate, and a brace on which the return spring is supported, wherein the brace is mechanically connected to the base element, so that an assembly enclosing the return spring in a cage-like manner is formed, and the exterior of the brace has a closed peripheral collar seated against a slanted sealing surface of a counterpart after installation and that is loaded by the return spring so that the brace is sealingly forced in the direction of the slanted sealing surface.
A thermostat insert comprising at least one restoring spring, a thermostatic working element with a working plunger which can be driven out of a housing of the working element counter to the force of the restoring spring, a main valve element and a bypass valve element which are connected to the working element which is moved when the working plunger is driven out of the housing, a basic element and an abutment, on which the restoring spring is supported, the abutment being connected mechanically to the basic element, with the result that an assembly is formed which surrounds the restoring spring in a cage-like manner, wherein, on its outer side, the abutment has a collar which is circumferential in a closed manner, bears against an oblique sealing face of a counterpiece after installation and is loaded by the restoring spring, with the result that the abutment is forced in a sealing manner in the direction of the oblique sealing face.
