Abstract
A thermostat construction having a valve unit for directing a pneumatic signal to a pneumatically operated control device in relation to the force differential between the temperature sensed by the temperature sensing unit thereof and the temperature setting of a temperature setting unit thereof, the construction having a lever pivotally mounted thereto and being operatively interconnected to the valve unit at a first portion of the lever and to the temperature setting unit and the temperature sensing unit at a second portion of the lever by a post-like member. The post-like member has a pivot section thereof pivotally interconnected to the lever at the second portion thereof to operatively interconnect the temperature setting unit and the temperature sensing unit to the second portion of the lever to compensate for any misalignment between the operating parts. The temperature setting unit comprises a bimetal member and the post-like member has a link pivotally mounted thereto and provided with a pin that bears against the bimetal member to pivotally interconnect the bimetal member to the link and, thus, to the post-like member.
