Claim:

In mechanism for the purpose described, a slide having a wrist pin on which is thereon on which is journaled the valve connecting rod in combination with a disk having guides thereon in which the said slide may move: a suitably journaled sleeve on which the said disk id fast; means for revolving the said sleeve from some moving part; a shaft within the sleeve; a connection between the shaft and the slide whereby the latter may be moved by the turning of the shaft.
