Transmission device for regenerative heat or refrigeration machine

摘要

The transmission device has two linear moveable pistons in a pressure-tight housing. Each piston is guided by a straight-line articulated system of the coupled gear-type. Both systems and both pistons are synchronized by a common crankshaft (23). The articulated system is formed as a four-bar linkage mechanism, each with an articulated member (30) with link guide (38), and a slide block (40) positioned on the crankshaft which engages into it. The link guide is open on one side.
