摘要： PURPOSE:To always form a good lubricating film, by arranging a back pressure feed oil hole to a rear side plate, communicating a feed oil passage to the rear part of a vane from said back pressure feed oil hole, interposing a thrust bearing in said feed oil passage and utilizing vane back pressure feed oil directly to lubrication for said thrust bearing. CONSTITUTION:Pressure oil, reaching a thrust bearing box 26 arranged between the rear side slide surface of a rotor 8 and rear side plate 6, is fed and flow divided to each slide part, containing a rear side thrust needle bearing 19, to perform lubricating action. The pressure oil partially passes through a gap, constituted between a rear end part 16 of rear side thrust race and rear side plate 5, to flow out to a rear side radial needle bearing 7, while passes through a gap, constituted between a rear side thrust race 18 and the rear side thrust needle bearing 19 and the rear side plate 6, to lubricate between the rear side thrust race 19 and rear side thrust needle bearing 19 and also lubricate the rear side slide surface of the rotor 8.

摘要： PURPOSE:To make it possible to perform the maintenance and inspection of a heat accumulation tank by a method wherein a heat medium pipe and a heat accumulating vessel are connected to each other through heat conductive ribs so that an undissolved part of a heat accumulating agent is reduced to a minimum. CONSTITUTION:Straight sections 3a of the heat medium pipe 3 are attached with a plurality of divisions of the heat accumulating vessel 4 divided by the heat conductive ribs 5. These ribs 5, the straight sections 3a of the heat medium pipe 3 and the heat accumulating vessel 4 are formed integrally with one another. In the case of the above structure in which the heat medium pipe 3 is provided adjacent to the heat accumulating vessel 4, the heat accumulating agent 2 does not remain undissolved so that the maintenance and inspection of the heat accumulating agent 2 in the heat accumulation tank can be performed easily.

摘要： PURPOSE:To smooth an action of a vane when the vane starts to run out as well as to diminish a frictional force within grooves of the vane, by forming, in a arc- shape the end of a vane opposite to its other and which is abutting to a cam ring. CONSTITUTION:A vane 7 is formed in such a way that its end portion, that is, a portion 7A abutting to a cam ring is formed in a conventional contiguration of arc- shape with a radius R, while its base portion, that is, an end face 7B of the opposite side to the position 7A abutting to the cam ring is formed in a arc-shape with a radius r(a half of the width of the vane). Therefore, the end face 7B of the vane 7 may be connected with the both end faces and this connecting portion may be formed in a curved surface.

摘要： PURPOSE: To sufficiently lubricate a surface of a swash plate at start of a compressor by providing a sub-oil sump at the lower part of a swash plate for dipping the lower part of the swash plate in an oil deposited therein at stop of the compressor and feeding back an oil deposited in auxiliary oil chambers during operation of the compressor into the sub-oil sump while the compressor rests.
CONSTITUTION: A sub-oil sump chamber 21 is provided at the lower part of a swash plate 13, that is, between mutually adjacent two bores of left and right cylinder blocks 2, 3, constituted in such a manner that the lower part of the swash plate 13 with an oil deposited therein is dipped while a compressor rests. A part of the oil floating in the state of mist in the sub-oil sump chamber 21 passes through communication holes 29, 30 into auxiliary oil chambers 25, 26 disposed around the sub-oil sump chamber 21 and is gradually concentrated and deposited therein. When the compressor stops, no oil enters the auxiliary oil chambers 25, 26 through the communication holes 29, 30 from the sub-oil sump 21 and the oil in the auxiliary oil chambers 25, 26 goes slow into the sub-oil sump 21 through small openings 27, 28. As sufficient oil in the sub-oil sump chamber 21 is ensured at start of the compressor, the surface of the swash plate may be well lubricated.

摘要： PURPOSE:To improve durability by a method wherein oil is separated from a sucked refrigerant and stored in an oil reservoir provided on a bottom, and a lubrication is carried out quickly at restart-up. CONSTITUTION:Lubrication is carried out fundamentally with an oil fed back into an inclined plate space 16 from an inlet port 15 together with a refrigerant. The oil having lubricated a sliding zone of an inclined plate 1 and thrust bearings 43, 44 in the inclined plate space 16 is splashed in the direction of the inner periphery of a shell by rotation of the inclined plate 1 and then reaches oil separation chambers 28, 29 through flow passages 20, 21 together with a low-pressure gas. The oil separated in said chambers comes to a rotary shaft 5, a part of the oil lubricates a front radial bearing 48 and the remaining oil flows into an oil reservoir 49 from a through hole 53. Lubricating property is thus improved.

摘要： PURPOSE:To restore lubrication speedily at the time of staring operation by providing a lubricant holding unit on the inner wall of a swash-plate chamber. CONSTITUTION:Lubricant which is scattered in the axial direction by its movement in the axial direction due to the rotation of swash plate 5 reaches the inner wall surface of swash plate chamber 4 of cylinder block 8 and flows into narrow hole 13. The lubricant which has flowed into the hole is in the state of being shut from the air pressure due to the movement of swash plate 5 in operation or the effect of the flow of the coolant so that it is held in the hole. On the other hand, when the operation is stopped, the lubricant held in narrow hole 13 flows down from the opening along the inner wall surface of swash plate chamber 4 and settles at the bottom of the chamber. Consequently, the lower part of swash plate 5 is immersed in oil and lubricated even when the operation is stopped for a long time. As a result, it is possible to form a sufficient lubricant film by a single rotation.

摘要： PURPOSE:To positively utilize oil foaming produced in a compressor at the activation thereof for effective lubrication even in the reactivation. CONSTITUTION:When a compressor has sufficient amount of refrigerant to display full refrigerating capacity in the freezing cycle, foaming phenomenon occurs due to the lowering pressure in a swash plate chamber 16 at the activation of the compressor. The foaming phenomenon increases th apparent volume of oil to several ten times. It also occurs in oil within an oil reservoir 25 to jet foamed oil from an orifice 26 into a swash plate chamber 16 as shown by arrow in the drawing. This oil is supplied to lubricate the surface of a swash plate 3. On the other hand when the amount of refrigerant decreases in the reactivation of compressor, the amount of refrigerant dissolved into oil in the swash plate chamber 16 decreases. However, when furan system refrigerant is used and a protective device for the compressor is provided, at least some degree of refrigerant is mixed into oil in the oil reservoir 25 at the reactivation of compressor and always foaming phenomenon occurs.
