油装置。 The opening of the cylinder is closed by a bearing that pivotally supports the rotating shaft, and a roller that fits on the rotating shaft is housed in the cylinder chamber formed by these so as to be eccentrically rotatable. The cylinder chamber is partitioned by abutting against each other, and a spring that elastically presses against the blade is housed in the spring chamber, and lubricating oil is pumped from the oil reservoir through the spring chamber by the pump action accompanying the reciprocating movement of the blade. An oil groove is provided in the end surface of the spring chamber, and an oil groove is provided in the end surface of the spring chamber,
This oil groove is covered by the flat part of the cap body, and as the blade reciprocates, lubricating oil is introduced from the oil groove into the spring chamber. The opening surface of the spring chamber is closed, and the lubricating oil led out from the spring chamber is temporarily stored, and a lead-out hole is drilled in a part of the circumferential surface of this cap part to guide the lubricating oil, and the lubricating oil is drawn out and guided from the circumferential surface of the bearing. A notch is cut out in the part to engage with a part of the peripheral surface of the cap part, and one end opening of the oil supply guide hole bored in the bearing is communicated with the above-mentioned lead-out hole in this notch, and the other end opening is connected to the rotation shaft. An oil supply device for a rotary compressor, characterized in that it communicates with an oil supply path.
