摘要： A scroll compressor is provided with a housing having a discharge chamber to which a high-pressure refrigerant is discharged from a scroll unit, a discharge path connecting the discharge chamber and an outlet port 78 of the housing, a separating device arranged in the discharge path and separating a part of the lubricating oil from the refrigerant, and a relief valve arranged in a downstream side of the separating device in the discharge path. When a pressure within the discharge path exceeds a relief pressure, the relief valve is opened so as to eject the refrigerant to an outer side of the compressor from the discharging path.

摘要： The present invention provides a compressor capable of supplying a lubricating oil stably to the refrigerant suction side of a compression section even if a lubricating oil is discharged into an oil storage chamber with great force. In this compressor, the oil storage chamber is provided so that two chambers of a first oil storage chamber and a second oil storage chamber communicate with each other, the lubricating oil discharged from a separation chamber is received by the first oil storage chamber, and the lubricating oil is supplied from the second oil storage chamber to the refrigerant suction side of the compression section. Therefore, even if the oil surface of the first oil storage chamber is disturbed by the force of the lubricating oil discharged from the separation chamber, the lubricating oil can always be supplied stably without hindrance to the supply of lubricating oil to the refrigerant suction side of the compression section.

摘要： A scroll-type compressor includes a housing including a suction chamber and a discharge chamber. The compressor also includes a fixed scroll including a first spiral element. Specifically, the fixed scroll is fixed to the housing, and a sealing member seals the fixed scroll and the housing. The compressor further includes an orbiting scroll including a second spiral element. Specifically, the orbiting scroll is positioned inside the suction chamber, and the first spiral element and the second spiral element interfit with each other to form a fluid pocket. Moreover, the compressor includes a driving mechanism for moving the orbiting scroll in an orbiting motion, a rotation prevention mechanism for preventing the orbiting scroll from rotating, and a first circumferential groove formed at a circumferential surface of the fixed scroll. The compressor also includes a second circumferential groove formed at a bottom surface of the first circumferential groove, and the sealing member closes an open end of the second circumferential groove, such that a first communication path passes through the second circumferential groove. The compressor further includes a second communication path lying at a lower portion of the fixed scroll. Specifically, the second communication path allows fluid communication between a lower portion of the discharge chamber and a lower portion of the first communication path. Moreover, the compressor includes a third communication path formed at an upper portion of the fixed scroll. Specifically, the third communication path allows fluid communication between an upper portion of the suction chamber and an upper portion of the first communication path.

摘要： A superior high-temperature strength aluminum alloy material is produced by consolidating rapdily solidified particulates of an aluminum alloy into a desired configuration, the aluminum alloy consisting of, in weight percentages, 4 to 15% Fe, and 0.5 to 8% V and the balance being essentially aluminum. The aluminum alloy may further contain at least one element selected from the group consisting of 0.5 to 8% Mo, 0.5 to 8% Ni, 0.3 to 8% Zr and 0.5 to 8% Ti and these additional components develop a further increased strength in the resulting formed materials. Since the consolidated aluminum materials above specified have a superior strength at high temperatures as well as moderate temperature without an expensive Ce, they are highly useful as economical heat-resistant materials for various applications, particularly for the fields where high strength at high temperatures and lightness of weight are required.
