Claims

[Claims for Utility Model Registration] ■ In a space enclosed by a cylindrical or elliptical cylinder and front and rear side plates joined to the end faces of the cylinder, a vehicle rotatably supported by the side plates. A rotor fixed to a drive shaft is accommodated, and a vane groove is formed over the entire width on the outer circumferential surface of the rotor or the inner circumferential surface of the cylinder, and the vane groove has a vane groove formed on the inner circumferential surface of the cylinder or the outer circumferential surface of the rotor. A vane slidingly in contact with the front, front and rear side plates is retractably housed to compress the gas, the rear side plate has a communication hole with the discharge chamber, the rear housing has a discharge hole, and the In a rotary compressor having an oil separation chamber between a rear side plate and a rear housing, separating oil is allowed to flow down between the communication hole and the discharge hole of the oil separation chamber and an inner wall surface of the rear housing. 1. A rotary compressor characterized in that a shielding plate is attached to a rear side plate or an inner circumferential surface of a rear housing, the shielding plate having a very small gap and being formed in a substantially airtight manner with the inner circumferential surface. ■ On the inner wall surface above the shielding plate of the rear housing,
The rotary compressor according to claim 1, which is a utility model, and is characterized in that it is provided with an appropriate number of protrusions or grooves that can guide oil downward. (2) In the seed compressor which has a communication hole in the upper part of the rear side plate and a discharge hole in the upper part of the rear housing, a guide plate capable of guiding refrigerant gas in the left and right direction is attached to the rear side plate facing the communication hole, and the guide plate is attached to the rear side plate so as to face the communication hole. The shielding plate is fixed to the lower part of the plate. - Utility model registration claim 1 or 2
Rotary compressor as described in section.
