VARIABLE STROKE/CLEARANCE MECHANISM

摘要

A variable stroke and clearance assembly includes a piston (3024) coupled to a rotating member (3056) and a support (3062). Motion of the rotating member varies piston stroke, and motion of the support piston clearance. The rotating member and support are coupled such that motion of the rotating member and support are related. The coupling is linear (3050, 3052, 3054), and the clearance is substantially zero at two stroke lengths. Alternatively (figure 60), the coupling is non-linear, and the clearance is near zero over a range of stroke lengths. The assembly is a compressor with an integral motor (3104), which includes a rotor (3116) rotating with the rotating member.
