摘要： A first bypass valve (27) that sets discharge capacity to 60% is provided in a first scroll 21 of an asymmetrical spiral-type scroll compressor. Also, a second bypass valve (40) that makes suction side and discharge side communicated with each other so that set load of the compressor becomes 50% is provided outside a scroll of the first scroll (21). In this way, by closing the first and second bypass valves (27, 40), effective load of the compressor is set to 100%. Also, by opening the first bypass valve (27) and concurrently closing the second bypass valve (40), the effective load of the compressor is set to 60%. Further, by opening both the first and second bypass valves (27, 40), the effective load of the compressor is set to 30%.

摘要： In a scroll compressor (A) configured such that an oil is supplied to a compression chamber (14) between fixed and movable scrolls (10), (11) and to bearings (28), (29) for a crank shaft (8), an electric motor (7) and an oil reservoir 1a are placed in a discharge chamber (22), a discharge port (11c) for discharging a gas compressed in the compression chamber (14) is formed in an end plate (11a) of the movable scroll (11), and the crank shaft (8) is provided at the inside thereof with a discharge gas passage (8e) for causing the gas discharged through the discharge port (11c) of the movable scroll (11) to flowinto the discharge chamber (22). The sucked gas is prevented from being heated by a heat loss of the electric motor (7) or the oil thereby increasing the performance of the compressor (A) and a rise in cost for separating the oil from the compressed gas can be prevented.

摘要： A discharge passage 15 which communicates with a discharge outlet 16 of a compressing section 3 and discharges compressed gas into a chamber S1 opposite to the compressing section with respect to a motor 2 is provided axially through a drive shaft 4 of the motor 2. An outward discharge pipe 17 is opened at a middle chamber S2 provided between the compressing section 3 and the motor 2 inside a hermetic casing 1. An effect of cooling the motor 2 by discharge gas can be fully exerted, so that possible temperature increase of the motor 2 is prevented to improve reliability and efficiency of the motor 2, and oil mixed in the discharge gas is separated.

摘要： A scroll type fluid machine is provided with a mechanism for injecting oil into fluid working chambers such that a precise amount of oil is supplied without using any capillary tube, instead using intermittent oil feed from an oil sump through a communicating passage into the working chambers. Within a sealed casing, a first scroll having a spiral ridge and a second scroll having a spiral ridge are interleaved forming working chambers therebetween. A precise amount of oil is supplied to the working chambers from an oil sump which is in flow communication with an oil feed chamber provided on the end face of a cylinder member which is in sliding contact with the end plate of the second scroll. The oil feed chamber is in intermittent flow communication with a communicating passage which intermittently connects the oil feed chamber to the working chambers as the second scroll revolves.
