ABSTRACT:
The invention relates to a thermostat unit adapted to be attached to a radiator valve of the type having a rotatable adjusting spindle and a surrounding ring shaped housing portion. The thermostat has a rotary knob unit with a body portion and a smaller diameter neck portion which connects to the valve spindle. The thermostat has a base unit with a supporting ring portion which surrounds said rotary knob body portion and a tightening ring portion which is attachable to the valve housing. The base unit supporting ring portion provides lateral or transverse support for the knob unit body portion to prevent breaking thereof when the knob unit body portion is subjected to large transverse forces resulting from accidental blows to which the knob unit body portion may be subjected.
