    摘要： A torque control apparatus for a compressor driven by a motor through a main shaft, in which variations of the rotation speed of the main shaft due to torque variations are detected at selected angular positions of rotation of the main shaft. Current values to be supplied to the motor for eliminating the rotation speed variations depending on the angular positions of rotation of the main shaft are computed and stored during at least one revolution of the main shaft, and, in the next revolution of the main shaft, that is, when the main shaft rotates then to a 360.degree. advanced angular position, the motor current is controlled on the basis of the current values supplied for at least one revolution of the main shaft, thereby eliminaitng variations of the rotation-speed of the main shaft.

    摘要： A scroll compressor comprises two scroll members, each of which has an end plate and a wrap formed on the end plate so as to extend perpendicularly therefrom, are meshed with each other, one scroll member being orbited with respect to the other without being self-revolved, to introduce a gas into working chamber. The working chamber is formed by these two scroll members, compresses the gas therein and then discharge the same to the outside. A seal mechanism for pressure-sealing between the working chamber or the suction side and a space on a rear surface of the orbiting scroll member is provided on the same rear surface, and also a pair of small-diameter ports for communicating the mentioned space and working chamber with each other are provided on the end plate of the above-mentioned scroll member, whereby the outer diameter of the scroll members can be minimized, and the axial opposed end surfaces of the two scroll members can be maintained in sealed condition.

    摘要： The compressor is characterized by a high pressure port provided in a rear plate at a position that the bottom portion of a vane groove of a vane which reaches a delivery port contacts the high pressure port, and low pressure ports provided, independently of the high pressure port, in the front and rear plates at positions so that the low pressure ports communicate with the high pressure port through the bottom portion of the vane groove of the vane between the low and high pressure ports only when the center of said vane groove is disposed between the high and low pressure ports so that the high pressure is fed intermittently to the low pressure port. In a region of rotation of the rotor where vane-tip pressing force is small, a high pressure from the high pressure port is applied to vane grooves as vane back pressure, and in the other region a relatively low pressure is applied thereto from the low pressure ports.
