Abstract

1. Thermostat for regulating a radiator valve, comprising a mounting base (1) having a securing flange (2), a rotating knob (12) which can be screwed so as to be held therein, the maximum rotating capacity of which relative to the mounting base is limited between two end positions by means of stops, and a temperature-dependent expansion system (16) mounted in the interior of the rotating knob, the rotating knob being provided with a releasable auxiliary adjustment device, which prevents the rotation of the rotating knob at a pre-determined set value and which has an unlocking button (35) and which is acted upon by a spring (36) and which is movable in a longitudinal groove provided on the outer periphery of the rotating knob and which has a radialy protruding projection, characterised in that the unlocking button (35) of the rotating knob (12) which is pressed radially outwards by the force of the spring (36) supported against the temperature-dependent expansion system (16), supports a projection (41) which has a serrated cross-section which protrudes radially outwards and which co-operates in a locking manner with wedge-shaped longitudinal grooves (42, 43), which are formed accordingly and which are mounted on the inner periphery of a co-axial, hollow cylindrical extension (10) of the mounting base (1), and one of which at least is formed as a blocking groove (43) with a correspondingly formed serrated cross-section, the flanks (44) of both serrated cross-sections being formed in such a manner that there is no restriction when there is reciprocal engagement when turning the rotating knob from greater set temperature values to lower ones, whilst when turning in the opposite direction to higher set temperature values there is a restriction of the rotating capacity, which is overcome by depressing the unlocking button (35) by disengagement, and that the maximum rotating capacity of the rotating knob (12) can be set selectively by means of limiting plates (30, 32), which form stops, and which are insertable in longitudinal openings (29) distributed radially on the periphery, and extending into the interior of the base area of the mounting base (1), and which limiting plates co-operate with a longitudinal rib (33) which is formed on the inner periphery of the rotating knob (12) and which projects radially inwards.
