摘要： A variable capacity scroll compressor includes a fixed scroll. The fixed scroll of the compressor includes a bypass flow path configured to connect a suction unit to a compression unit, a cylinder space provided on the bypass flow path, and an on/off valve disposed to be movable back and forth in the cylinder space to open/close the bypass flow path according to a difference between a discharge pressure of the discharge unit and a suction pressure of the suction unit. Thus a capacity of the compressor may be reduced by connecting the suction unit to the compression unit under a low load condition in which a difference between a discharge pressure and a suction pressure is relatively less.

摘要： A tip seal for scroll wraps in a scroll compressor is provided. The tip seal may include surface features to form a tortuous flow path in a seal groove of a scroll wrap. The surface features can help form one or more contraction and/or expansion areas in the tortuous flow path. The tortuous flow path can help provide resistance to fluid flow and help reduce leakage through the seal groove.

摘要： The present invention comprises two complementary gear wheels each of which have a plurality of vanes fixed to the interior faces thereof. The vanes are interlocked in overlapping relationship and the gears are free to rotate independently of one another at different speeds so as to cause the gaps or chambers between the vanes to vary depending upon the changes in the relative speed of the two wheels with respect to one another. Various means are provided for driving the two wheels independently of one another at varying speed ratios. Chain and sprockets may be used, or complementary gears of varying shapes and having different numbers of lobes may be used to accomplish different patterns of movement of the two wheels with respect to one another. Furthermore, variable drive means may be provided for driving the two wheels so as to provide positive control of the variance in the movement of the two wheels.

摘要： The invention reduces a centrifugal force of an orbiting scroll which acts on an auxiliary crank mechanism. A crank pin which is eccentric from a main shaft portion is formed in a drive shaft and attached to an orbiting bearing which is provided in a back face side of an orbiting scroll. The main shaft portion of the drive shaft is rotatably supported by a main bearing. An internal gap of the main bearing is set to a value which is larger than a value obtained by subtracting the double value of an eccentric amount difference between an eccentric amount of an auxiliary crank shaft and an eccentric amount of the drive shaft from an internal gap of the orbiting bearing.

摘要： A fluid machinery is disclosed which is able to assure a large compression volume without an increase in size and achieve high compressibility by suppressing leakage from sealing, thereby improving the reliability. In the fluid machinery, a second spiral 13 having a spiral inner engaging surface 17 formed to have a stepped shape in section is engaged with a first spiral 15 having an outer engaging surface 21 with a stepped sectional shape which rises upwardly from an outer peripheral side to a central side in a spiral manner, so that sealed spaces 25 are formed to cause reduction in volume of sealed spaces in both radial and height directions from a peripheral side to a central side. A closed spaces 35 having an inclination surface 19 is formed between a stepped surface of the outer engaging surface 21 of the first spiral 15 and a stepped surface of the inner engaging surface 17 of the second spiral 13. A spiral member 37 having a slant surface 39 which engages always with the inclination surfaces 19 is provided in the sealed spaces 35 so as to seal the lower pressure sealed spaces 25 and the higher pressure sealed spaces 25.
