The crank mechanism of a gas meter with temperature compensation, particularly a bellows gas meter, containing a rotating part whose axis is at the same time the axis of rotation of the crank disc and at least one crank element connected with the temperature - dependent compensation elements, wherein the crank element (3) is directly coupled with the compensation element (10) and also indirectly, through slide (7), coupled with the compensation element (4). The crank element (3) is fixed at the free end of the compensation element (10), which in turn is fixed in the slide (7). Slide (1) has a straight line guide in the crank disc (2) and an articulated joint connection with the inclining arm (6) of the compensation element (4). The compensation element (4) is fixed in a non-rotational manner in the crank disc (2) and has an inclining arm (6) with a limited displacement capability for temperatures lower than the basic temperature due to a stop element (12) fixed in the crank disc (2). Both compensation elements, element (4) and element (10), are 'U'-shaped thermal bi -metals. |
