摘要： In a scroll compressor, the side of the orbiting end plate away from the compression chambers is slidably supported by an annular protusion formed in the frame. A lower pressure chamber is formed on the radially outer side of this annular protrusion, and an Oldham's ring is fitted inside the lower pressure chamber.

摘要： In a scroll compressor for compressing gas a scroll unit having stationary and orbiting scroll members with interfitting spiroidal wraps is hermetically enclosed in a housing. During operation, a compression chamber defined between the scroll chambers is given a high pressure, and the space in the housing below the orbiting scroll member is given a low pressure atmosphere. A motor housed in the low pressure atmosphere rotates a drive shaft. This drive shaft causes the orbiting scroll member to orbit. A passage is provided in the orbiting scroll member to connect the low pressure atmosphere and the compression chamber. A thrust reduction mechanism is supported by the housing in the low pressure atomophere. The thrust reduction mechanism receives the pressure of the compression chamber via the passage.

摘要： In a scroll compressor, at least one suction port for gas is opened in a stationary end plate which has a spiral wrap. Gas is drawn directly into the compression chambers from the suction port. In addition, the suction port has an opening straddling both the radially extending surface of the stationary end plate at the outermost circumference of the compression chambers and the compression chamber side wall that is perpendicular to the radially extending surface, and the opening area of the suction port is relatively large.

摘要： A scroll compressor has a channel formed in a compressor member such as main shaft, frame, orbital scroll member, through which lubricating oil can pass easily from the higher pressure side to the lower pressure side under flow control between sliding surfaces of the compressor members without reduction in the sealing between the higher pressure side and the lower pressure side, whereby injecting sufficient lubricating oil between the scroll members improves both the sealing and the lubricating between the scroll members.

摘要： A scroll compressor includes a casing, an electric motor and a compressor unit housed in the casing and the compressor unit comprises a movable member having a first scroll blade driven eccentrically by the electric motor and a structural member having a second scroll blade encasing the movable member so that the first scroll blade revolves around a central axis of the compressor with a predetermined radius of revolution, while the first blade is maintained in sliding contact with the second blade. The two scroll blades are formed by drawing a series of semicircles alternately around a first point and a second point spaced apart from the first point. An internal end portion of the first and second scroll blades includes a planar surface disposed perpendicular to a line interconnecting the first and second point.

摘要： A helical-blade fluid machine maintains a low-pressure atmosphere in a closed casing (1) and secures a proper lubrication state for a compression mechanism (9). The fluid machine has a drive mechanism (7) that is installed at an upper or lower part of the casing and consists of a stator (11) and a rotor (15). The compression mechanism is installed at the other part of the casing. The compression mechanism has a cylinder (23) and a roller (25), which is swayed with respect to the cylinder by the drive mechanism. A helical blade (39) having unequal pitches is arranged on the roller, to define compression chambers (41). This arrangement lowers the head of lubricant. An intake pipe (5) feeds gas into the casing so that a low-pressure atmosphere fills the casing.

摘要： A fluid compressor comprises a rotary member, a cylinder, and a closed casing for receiving the rotary member and cylinder. The rotary member and cylinder are relatively turned so that a fluid is drawn into work chambers through a suction port, successively compressed and conveyed toward a discharge port through the work chambers, and discharged outside. The fluid compressor is provided with a control valve means. When pressure in the work chambers exceeds a predetermined value during the compressing process, the control valve releases the pressure through a discharge or suction end of the cylinder, or to the inside of the casing.
