ABSTRACT:
A rotary-vane machine, has a stationary tubular housing having a lubricated pump with an oil carter, and an oil-free section, with two pairs of ports through which a working medium enters or exits, a housing cover plate, a sun gear attached to a boss, a bearing and oil transferring member, a cover disc attachable to the end of the oil-free housing section, and a tubular rotor inside of which are fixedly attachable, two tapering vanes rotatable, together with the rotor, at a uniform speed. The machine has a first rotor end plate, attached to a drive shaft, a second rotor end plate attached to the rotor, a hollow oscillatable main shaft in bearings in the first and second end plates is concentric with the rotor, two substantially flat vanes fixedly attached to opposite sides of the hollow shaft define with, the hollow shaft, the tubular rotor, the tapering vanes and the first and second end plates, four chambers, a shaft rotatable in bearings mounted in the second end plate, and a connecting rod having a big end and a small end. The big and small ends are associated with the eccentrics and a rocker arm attached to the reduced main shaft end. Drive shaft rotation at uniform speed rotates the rotor at the same uniform speed, while oscillatory motion is superposed on the hollow shaft, whereby the chambers to successively vary between minimum and maximum volume.
