Abstract: A refrigeration cycle device includes: a casing that configures the outer contour of an outdoor machine, has a machine chamber and a blowing chamber formed therewithin, and has formed an introduction hole for introducing outside air into the machine chamber; a partition plate that partitions the interior of the casing so as to demarcate the machine chamber and the blowing chamber; a refrigeration cycle circuit, of which at least a portion is disposed in the machine chamber, and through which a combustible refrigerant circulates; and a blower disposed in the blowing chamber. A blow-through hole connecting from the machine chamber to the blowing chamber is formed in a bottom part of the partition plate. The outside air introduced into the machine chamber from the introduction hole flows through the blow-through hole and into the blowing chamber, and is sent outside the casing from a blow-out opening formed in the blowing chamber.

Abstract: A compressor includes a compression mechanism part for compressing refrigerant sucked from an outside of the hermetic container and discharging compressed refrigerant to a discharge space, an electric motor part composed of a stator and a rotor, facing a first space which is at an opposite side of the discharge space with respect to the compression mechanism part in the hermetic container, for driving the compression mechanism part through a main shaft, a passage at an external circumferential side of the compression mechanism part, for connecting the discharge space with the first space, and a fan provided at an end of the rotor, facing the first space. The refrigerant discharged into the discharge space passes through the passage at the external circumferential side of the compression mechanism part to reach the first space, and passes the fan to be discharged to the outside of the hermetic container.

Abstract: A rotary compressor having a piston provided integrally with a blade is contained in a hermetic vessel which is operated at a suction pressure of the rotary compressor and not to discharge pressure. The rotary compressor includes a compression mechanism portion having a cylinder which includes a suction port formed in a cylinder chamber, a piston which eccentrically revolves in the cylinder, a blade which is integrally formed with the piston and partitions the cylinder chamber into a high pressure chamber and a low pressure chamber, and a driving shaft for revolving the piston.

Abstract: A scroll compressor comprising a fixed scroll, a rotating scroll, a compliant frame for supporting the rotating scroll in an axial direction and a main shaft for driving the rotating scroll in directions of radiuses of the rotating scroll, and a guide frame fixed to a hermetically sealed vessel for supporting the compliant frame in the directions of its radiuses, wherein the rotating scroll is slidable in the axial direction by sliding of the compliant frame on the guide frame; a space is formed between the compliant frame and the guide frame; and a pressure in the space is made to be a pressure higher than a suction pressure and the same as a discharge pressure or less, whereby relief of the rotating scroll is avoidable to quickly and constantly realize a state of normal operation.

Abstract: A scroll type compressor which includes a compression unit, a crankshaft having an oil passage therein, and an electric motor stator having an oil return hole. An oil pump feeds oil into the oil passage of the crankshaft, and an oil drain tube receives return oil from the compression unit and feeds the oil to the oil return hole of the electric motor stator. The drain oil tube advantageously includes an upper nonflexible drain opening which receives oil from the compression unit. The oil then passes through a nonflexible portion which includes a bend or bent portion, and then to a flexible portion which extends from the elbow into the oil return hole of the electric motor stator.

Abstract: A reliable scroll-type compressor is provided which, even when the compressor is rotated in the reverse direction by the erroneous connection of the power source terminals for example, is prevented from establishing a vacuum state within the compression chamber and no damages occur in the addendum of the stationary scroll and the orbiting scroll. The compressor includes a gear pump which includes a pump case and a pump port. The arrangement of the present invention is such that the pump case alone rotates by 180 degrees upon the reverse rotation of the motor, so that lubricating oil which is at the bottom of a hermetic vessel can be ensured to be supplied by the gear pump to each sliding portion of the compressor.

Abstract: A reliable scroll-type compressor is provided which, even when the compressor is rotated in the reverse direction by the erroneous connection of the power source terminals for example, it prevented from establishing a vacuum state within the compression chamber and no damages occur in the addendum of the stationary scroll and the orbiting scroll. Since the sliding surface of the slider is arranged to have an angle so that the slider is moved therealong in the direction in which the revolution radius of the orbiting scroll of the compressor is decreased, a clearance is generated between the stationary scroll and the orbiting scroll upon the reverse rotation.
