Scroll compressor
First Claim
1. A scroll compressor in which a fixed scroll part and an orbiting scroll part are meshed with each other to form a compression chamber, said orbiting scroll part is allowed to orbit in a circular orbit while restraining said orbiting scroll part from rotating by a rotation-restraint mechanism, a refrigerant is sucked, compressed and discharged while continuously varying a capacity of said compression chamber, whereinan oil supply passage is formed in a suction space of said fixed scroll part, and said suction space is provided with an oil collision part, whereina side surface of said oil collision part on the side of a refrigerant passage is a concave curved surface, one of end surfaces of said curved surface is formed on an extension surface of a suction pipe connected to said suction space, an intersection angle between a tangent of said one end surface of said curved surface and a tangent of the other end surface of said curved surface is an acute angle.

Abstract
According to the present invention, an oil supply passage is formed in a suction space of a fixed scroll part, and an oil collision part is provided in the suction space. The oil collision part is provided in the suction space, an amount of oil to be supplied is controlled, refrigerant and lubricant oil are sufficiently mixed with each other. Tangents of ends of the oil collision part are made acute angle to smoothen the flow of the refrigerant.
