Abstract: A scroll compressor is provided which has favorable assembling property, does not require a thrust bearing, has a bearing structure for bearing a compression section at both sides thereof and has a simple structure of a scroll.

Abstract: A scroll compressor includes a compression section having an orbiting scroll with volutes that are substantially symmetrically formed on both surfaces of an orbiting base plate. A main shaft penetrates through and is fixed to a center portion of the base plate. A pair of fixed scrolls is placed on both surfaces of the orbiting scroll, and has volutes which correspond to the respective volutes of the orbiting scroll to form compression chambers. The main shaft has a notch part which is formed at a portion penetrating through the orbiting scroll and fixed scrolls. A slider is provided which has an eccentric hole including a flat slide surface corresponding to the notch part. The slider is fitted to the main shaft where the notch part is formed. The slider is made slidable in a direction orthogonal to a length direction of the main shaft by the flat slide surface.

Abstract: A scroll compressor that has reduced leakage loss and high efficiency includes an orbiting scroll that has spiral teeth on two surfaces, and a fixed scrolls that face the surfaces of the orbiting scroll and that have spiral teeth that intermesh with the spiral of the orbiting scroll. Tip seals are mounted only to a spiral tooth of one of the fixed scrolls that intermeshes with a spiral tooth of the orbiting scroll and a spiral tooth of the orbiting scroll.

Abstract: An air conditioner including an outdoor unit, indoor units, and a relay device for connection between the outdoor unit and each of the indoor units. The outdoor unit includes an outdoor heat exchanger, a compressor for pressurizing a refrigerant of or including carbon dioxide, and a first switching member for switching flow direction of the refrigerant through the outdoor heat exchanger. Each of the indoor units includes an indoor heat exchanger and first flow controller in fluid communication between first and second pipe connection ports. The relay device includes second switching members, each of the second switching members selectively connecting the first pipe connection port of a respective indoor unit with the first or second connection end of the outdoor unit.
