摘要： PROBLEM TO BE SOLVED: To elongate the service life of a crank shaft (18) of a compressor.
SOLUTION: This crank shaft (18) used in the compressor including a lip seal, includes a first material composing the crank shaft (18), a region (49) of the crank shaft kept into contact with the lip seal, and a protecting part for protecting the crank shaft (18) from abrasion by frictional contact with the lip seal. The protecting part includes a second material added to the crank shaft (18), and the second material forms a hardened face of the crank shaft (18) in the region. The protecting part preferably has the configuration of an abrasion-proof sleeve (28) on the crank shaft (18). The abrasion-proof sleeve (48) is composed of the second material of lower abrasion in comparison with the first material when it is kept into contact with the lip seal, formed independently from the crank shaft (18), and detachable to be replaced.

摘要： PROBLEM TO BE SOLVED: To improve operability by constituting a positioning driving mechanism of a variable diffuser for a centrifugal compressor so as to rotate a cylindrical member through meshing of a pinion shaft and a rack gear by a rotary driving means, and arranging a movement limiter to restrict a movement of the cylindrical member. SOLUTION: A centrifugal compressor 10 has an impeller 12 to accelerate refrigerant vapor, a diffuser 14 to convert kinetic energy of the refrigerant vapor into pressure energy and a delivery plenum 16 to collect delivery vapor. The diffuser 14 is a variable structure, and contains an inside ring 40, an outside ring 42, a ring support mechanism 35 and a positioning driving mechanism 121. The positioning driving mechanism 121 is constituted so as to rotate the inside ring 40 in the circumferential direction on the inside of the outside ring 42 through a rack gear 123 meshing with a pinion shaft 126 by an actuator 128. In this inside ring 40, a movement is restricted between first and second positions by a movement limiter.

摘要： PROBLEM TO BE SOLVED: To extend lifetime of a lip seal 38 of a compressor.
SOLUTION: This lubricating device lubricates the lip seal 38 of a crankshaft having a wearing surface using a lubricant used in the crankshaft 18. The lubricating device includes a compressor housing section 32, and the lip seal 38 is fixed in the compressor housing section 12 so as to contact with the crankshaft 18 and a structure of the compressor housing section 32 for sufficiently providing the lubricant to the surface of the lip seal 38. The structure includes a boa 40 having a reservoir for maintaining the lubricant in a contacting state with the lip seal 38.

摘要： PROBLEM TO BE SOLVED: To reduce oil leakage in a system using shaft seals.
SOLUTION: The compressor oil diversion and collection system used in a compressor has a housing, a crankshaft having shaft seals, refrigerant and a compression device for compressing the refrigerant. The system includes a shaft sealing mechanism that uses a lubricant for preventing compressor refrigerant from leaking out of the compressor housing and has a space (40) where the lubricant collects. A diversion mechanism is deployed for directing excess amounts of the lubricant from the space (40) to a receiver for receiving the excess amounts of the lubricant from the diversion mechanism. The receiver may be in the form of an internal cavity (53) which includes a removable cartridge (54) located in the cavity for collecting the excess amounts of said lubricant, an external collection reservoir or an external drainage tube.

摘要： A backlash adjustment mechanism comprises a housing 130 having a cylindrical body positioned concentrically about a first centerline 127 and having a bore 129 disposed axially through the body positioned about a second centerline 131. A drive shaft 126 is rotatably disposed concentric with the second centerline within the bore. An inner ring is positioned such that it operably engages a pinion gear 124. The housing 130 is rotatably operable to effect an adjustment of the backlash between the pinion gear 124 and a rack gear 123.
