PURPOSE:To prevent generation of heat and abrasion of a slider in a compressor provided with the freely turning slider, which slides a vane only diametrically, in eccentricity with respect to a main shaft, by forming an oil jet stream passage, which puts the interior and the exterior of a rotor in communication with each other, on the side of a vane. CONSTITUTION:A slide groove is formed radially in the central part of a vane 3, while a slider 2 engaged with said groove is provided so as to freely furn round a point in eccentricity with respect to the rotary shaft of a rotor 1. On the other hand, an oil jet stream passage 11, which puts the interior and the exterior of the rotor 1 in communication with each other, is formed on the side of the vane 3. The length of said passage 11 is set so as to put the interior and the exterior of the rotor in communication with each other only during an intake stroke of a compressor. Since inhalant gas is inhaled from the interior of the rotor 1 during said stroke, the slider 2 is cooled and lubricated by oil contained in inhalant gas. |
