摘要： A vane-type rotary machine for use as a compressor, pump or the like. The rotary machine has a cam ring with an inner peripheral contour expressed by an epitrochoid-like curve having at least one lobe, a cylindrical rotor having a plurality of vane grooves and contacting the inner peripheral surface of the cam ring, and vanes slidably received by the vane grooves and adapted to slide on the inner peripheral surface of the cam ring as the rotor rotates. The inner peripheral contour of the cam ring is corrected or modified in accordance with the amount of offset of the vanes in such a manner as to suppress the lateral reactional force applied to the vanes thereby to reduce the friction loss during sliding of the vanes in respective vane grooves, while making the sliding movement of the vanes approach a movement in accordance with a sine wave curve, thereby to diminish noise, thermal loss and mechanical damage which are attributable to irregularity of movement of the vanes.

摘要： The variable capacity swash plate compressor of the present invention includes a rotary swash plate having an eccentric mass located opposite to the driving point of the swash plate with respect to the axis of the same. The mass distribution in the rotary swash plate is established such that, within a range in which the piston stroke is less than a predetermined value, a moment about a pivot point produced by the rotation of the swash plate becomes larger than a moment produced by the reciprocating motion of pistons, piston rods and the like and acting upon the swash plate, while, within a range in which the stroke is larger than the predetermined value, the former moment becomes smaller than the latter moment. Accordingly, it is possible to provide a compressor of the type in which its capacity control characteristics are improved over a wide shaft speed range.

摘要： A refrigeration system includes a variable-capacity compressor having a compression chamber for sucking and compressing a refrigerant and a crankcase surrounding a swash plate forming a drive portion for suction and compression, and a passage through which the refrigerant discharged from the outlet of the compression chamber passes at least through a condenser, an expansion means and an evaporator and is sucked into the inlet of the compression chamber of the compressor, the capacity of the compressor being changed by slanting the swash plate during its rotation. A pressure control device is provided in a refrigerant passage between the evaporator and the suction valve of the compressor whereby the pressure upstream thereof is controlled in such a manner that it does not decrease below a predetermined value, thereby preventing frosting of evaporator fins. A point partway along the passage upstream from the pressure control device and the crankcase of the variable-capacity compressor are communicated so that the capacity of the compressor may be controlled without controlling the pressure in the crankcase.

摘要： A variable displacement compressor has a sleeve axially slidably mounted on an axial drive shaft and a swash plate tiltably connected to the sleeve. The angle of the tilt of the swash plate is variable by an axial movement of the sleeve and a movement of the swash plate along a guiding cam track to vary the compressor displacement. The guiding cam track is provided by a cam groove having a form of a closed loop and formed in a driving plate drivingly connected to the drive shaft and to the swash plate to transmit the torque of the drive shaft to the swash plate. A fulcrum pin is provided on the swash plate and engaged in the cam groove and is movable along the guide groove toward the drive shaft as the angle of tilt of the swash plate is decreased.

摘要： An electromagnetic clutch having an energizing device including a cylindrical yoke assembly composed of a yoke member and a yoke holder, and a winding housed in the yoke assembly. The yoke member has an outer cylindrical wall and an inner cylindrical wall constituting a double wall cylindrical structure, and a doughnut-shaped bottom wall connecting the outer and inner cylindrical walls together. The outer cylindrical wall is tapering in going from the bottom wall toward the upper end, and the inner cylindrical wall has a constant thickness lower portion of a predetermined height contiguous with the bottom wall and a tapering portion contiguous with the constant thickness lower portion and having its thickness successively reduced in going toward the upper end. The inner cylindrical wall has an annular groove formed on its inner circumferential surface in its constant thickness lower portion. When the yoke member and the yoke holder is assembled, the yoke holder is force fitted to the yoke member and a clamping force is exerted on the yoke assembly in such a manner that the latter is plastically deformed to have its material flow into the annular groove of the yoke member to form a joint, whereby the yoke member can be firmly fitted to the yoke holder.

摘要： A swash plate type compressor including a partition plate mounted in a side cover for axially partitioning the interior of the side cover into two portions. One of said two portions interposed between the partition plate and a valve plate functions as a high pressure chamber, and the other portion interposed between the partition wall and a bottom wall surface of the cover functions as a silencing chamber. A compressed refrigerant discharged from cylinder bores and introduced into the high pressure chamber is discharged from the high pressure chamber through the partition plate into the silencing chamber where pulsations of pressure are removed from the refrigerant.By directing the compressed refrigerant discharged from the high pressure chamber toward the center of the silencing chamber and by drawing off the refrigerant from the center of the silencing chamber and introducing same into the refrigerant cycle, increased effects can be achieved in silencing noises.
