ABSTRACT:
An improvement for a variable volume device in the form of a rectilinear case having disposed therein a rectilinear outer piston structure and a rectilinear inner piston structure within the outer piston structure, the inner piston being carried for rotation on a crank shaft and in turn inducing a reciprocal movement of the outer piston structure in the case, the improvement comprising rollers positioned between the outer piston structure and the case, and the inner piston structure and outer piston structure to facilatate thrust and force accomodation therebetween, and sealing strip means positioned in sealing relationship between the outer piston structure and rectilinear case, and inner piston structure and outer piston structure, and particularly an embodiment in which the sealing strips means of the inner piston structure bear against the side portion of the outer piston structure sealing ring means and a bearing plate positioned to support the rollers, whereby the rectilinear innerrunning pistons may be effectively and reliably mounted for relative motion ensealed to define variable volume portions in the device.
