Abstract
Key lever works against a spring and has a valve on one sector and on a second connects to the key. A third sector angled relative to the second also carries a valve and forms a separate key lever which is hinged to the main lever and sprung into the valve-closing position. The leaf load spring (27) should be on the first, valve-carrying (5) sector to press the hinge-connected key lever (12) onto an adjustable end stop (26) used to set the angle of lever to the main key lever (1). The spring acts on the hinged part (20) of lever enclosing the main lever.
