A compressor, which is cooled by cooling medium, includes a compression chamber (26), a first cooling chamber (41) and a second cooling chamber (52a). In the compression chamber (26), gas is compressed and then discharged therefrom. The first cooling chamber (41), in which the cooling medium flows, is provided so as to adjoin the compression chamber (26) for cooling the gas in the compression chamber (26). The second cooling chamber (52a) adjoins the first cooling chamber (41). The second cooling chamber (52a) has a gas passage (53) in which the discharged gas flows and a medium passage (54) in which the cooling medium flows. The medium passage (54) is arranged so as to restrain transmission of heat of the discharged gas in the gas passage (53) to the cooling medium in the first cooling chamber (41).

A scroll type compressor has a housing, a fixed metal scroll member and a movable metal scroll member. The fixed and the movable scroll members each have a base plate and scroll wall extending therefrom. The fixed scroll member is fixed to the housing. The movable scroll member engages the fixed scroll member to trace an orbital motion when driven by a crank mechanism. The scroll members define compression chambers. Resin tip seals are respectively provided on distal ends of the scroll walls and slidably engage the metallic surfaces of the facing base plates. The tip seals seal the compression chambers. A resin coating layer is formed on a region of at least one of the end surfaces of the base plates that is not contacted by a tip seal.

A pump mounting structure is disclosed. The structure includes a mounting surface (Bd1) on a body (Bd) having an insertion recess (51), and at least one mounting member (41 b) having a mounting portion (43) inserted into the insertion recess (51). The mounting portion (43) has an outer surface (43a) and an insertion hole (42) through which a bolt (B) is inserted. A first gap (S1) is formed between the insertion hole (42) and the bolt (B). A second gap (S2) is formed between the outer surface (43a) of the mounting portion (43) and an inner surface (51a) of the insertion recess (51). A seal member (48) is disposed on an open side of the insertion recess (51).

摘要:
A scroll type compressor includes a fixed scroll member (20) and a movable scroll member (24) to define compression chambers. The movable scroll member orbits relative to the fixed scroll member to compress gas in the compression chambers. The compressed gas is discharged to a discharge port (20d). The compressor also includes a filter chamber (44) and a cooling chamber (32). The filter chamber communicates with the discharge port for accommodating a first filter (55) to at least partially filter the compressed gas. The cooling chamber is located adjacent to the filter chamber for containing coolant fluid that cools the compressed gas in the filter chamber.
摘要:
A compressor has a compression unit for compressing gas to a desired pressure, a drive shaft (25) and a balancer (30,31). The drive shaft (25) is connected to the compression unit for driving the compression unit. Imbalance on the drive shaft is generated due to movement of the compression unit. The balancer (30,31) is mounted on the drive shaft and includes a main portion and adjustable portion for correcting the imbalance on the drive shaft. Preferably, at least one of the weight and the shape of the adjustable portion is adjustable.
