摘要： Fixed scrolls 4, 5 are supported so to be movable axially relative to an orbiting scroll 6, so that a proper space is kept between wraps 4a, 5a and 6a to avoid an excessive load in the contacting area. Further, an end portion of an outer curve of the wrap 6a of the orbiting scroll 6 is formed to come close to or coincide to an outer edge of a panel 6f of the orbiting scroll 6 and an Oldham's coupling is accommodated in a concave groove 6e formed on an outer circumference surface of the panel 6f, so that the size of the scroll compressor is reduced.

摘要： A scroll compressor has an orbiting scroll which operatively meshes with a stationary scroll to define compression chambers therebetween. This orbiting scroll is driven by an electric motor through a crank-shaft, and makes an orbiting movement while being prevented from rotating about its own axis by a rotation preventing member. The crankshaft is journalled by at least two sliding bearings which are arranged respectively on the both sides of the electric motor, and the mast remotely distanced bearing from the orbiting scroll has a self-aligning function which enables it to change its attitude in accordance with any inclination of the crankshaft. Further, a balance and a counter weight are provided on the crankshaft to counterbalance the centrifugal force produced by the orbiting scroll and the inertial force produced by the rotation preventing member.

摘要： A horizontal-installation-type scroll compressor requiring small installation space adopts a technique which can reduce the amount of refrigerating machine oil circulating through the refrigeration cycle. By using this scroll compressor, an air conditioner is provided whose unit body has a reduced depth and which has satisfactory ventilation efficiency and cyclic efficiency.The scroll compressor includes a closed container which is separated into a section lodging an electric motor and a compression mechanism and a section where a discharge pipe is provided. Refrigerating machine oil is stored in the section including the discharge pipe in order to ensure the requisite amount of refrigerating machine oil. An oil separation mechanism is provided in the passage of the refrigerant gas so that refrigerant gas containing little amount of refrigerating machine oil may be sent out from the discharge pipe. Further, electrical parts and this scroll compressor are arranged below a heat exchange section equipped with a heat exchanger and a centrifugal fan, thus forming an outdoor unit.

摘要： A rotary compressor has a compression chamber defined by a rolling piston which is eccentrically rotated in a cylinder by a rotary shaft including an eccentric crank portion, and by a blade which slides in a groove formed in the cylinder and of which the tip contacts an outer-peripheral surface of the rolling piston. In such a rotary compressor, abnormal wear in the contact portion between the rolling piston and the blade can be prevented as follows: Assuming that the rotation angle of the rolling piston when the blade is located at a start position of reciprocating motion is zero degrees, the contact surface of the blade which is in contact with the rolling piston is formed to have a curvature of substantially zero and as a flat surface when the rotation angle of the rolling piston is about 90 degrees and about 270 degrees and the pressing force of the blade with respect to the rolling piston reaches the maximum value; and also, a material which has an elastic modulus lower than that of the material of the rolling piston which is highly self-lubricative is used for the blade.
