摘要： In a scroll compressor, a fixed scroll (3) and a movable scroll (5) each having a spiral body are engaged with each other, grooves (13, 14) extending along the spiral shape of the spiral body are formed on the forward end surface of the spiral body of at least either one of the fixed scroll and movable scroll, and tip seals (11, 12) are disposed in the grooves so as to project from the forward end surface and be slidable on the bottom plate surface of the other scroll facing the forward end surface. The tip seals have large projection parts (17, 18) with a larger amount of projection from the forward end surface and small projection parts (19, 20) with a smaller amount of projection from the forward end surface, and the large projection parts and small projection parts are arranged alternately in the direction along the spiral shape of the spiral body. The scroll compressor does not produce an excessive load at the end of the wall of the scroll while achieving the same sealability as in the case of conventional structures, i.e., the efficiency of the compressor can be improved.

摘要： A screw compressor (10) provided with a compressor body (11), an oil supply tank (13), an oil supply line (60), and an oil recovery line (59), wherein the screw compressor is also provided with shaft seal sections (28, 41) located on opposite sides, in the direction of shafts (26, 38), of a compression chamber (24) of a screw rotor (25) and preventing both mixing of oil in bearings (27, 39, 40) into a compression chamber (24) and leakage of process gas from the compression chamber (24), a suction-opening return line (52) for interconnecting the shaft seal section (41) on the discharge side of the compression chamber (24) and a suction opening (17) of the compressor body (11), a supply-process-gas communicating line (61) for interconnecting the suction opening (17) of the compressor body (11) and the upper part of the oil supply tank (13), and a shaft seal section (53) for dividing between the inside of the compressor body (11) and an atmospheric environment. The non-lubricated screw compressor (10, 70, 80) has the shaft seal sections (28, 41) which is inexpensive and highly reliable, which can prevent damage to the bearings (27, 39, 40) due to a reduction in the viscosity of lubricating oil, and which can prevent liquefaction of heavy hydrocarbon in a discharge system.
