One or more techniques and/or systems are disclosed for a gas compressor assembly. The gas compressor assembly may be comprised of a crankcase body that encloses a crankcase chamber. This crankcase chamber may connect to an internal fluid line in a manner that allows fluid communication. The internal fluid line may be specifically designed to direct discharge gas through the crankcase body, a process which may heat any liquid accumulated in the crankcase chamber, potentially converting it into a gaseous form.

A reciprocating compressor may include a ball bearing positioned between a thrust surface of a cylinder block and a thrust surface of a crankshaft. The ball bearing may include a ball cage in a ring shape, a plurality of balls rotatably coupled to the ball cage, at least one washer positioned at least one of between the thrust surface of the cylinder block and the plurality of balls and between the thrust surface of the crankshaft and the plurality of balls, and a rotation preventing portion that limits rotation of the washer with respect to the corresponding thrust surface. According to a reciprocating compressor having the rotation preventing portion, as relative rotation of the washer with respect to the thrust surface of the cylinder block and/or the thrust surface of the crankshaft is restrained even if a rotational force higher than a viscous force acting on the washer is applied because a viscosity of oil is lowered, it is possible to eliminate the problem of deterioration of reliability and performance of the compressor.

A reciprocating compressor with a head-holding turret in the upper portion of which one or more recesses, open to the outside, are defined, which reduce as much as possible the contact surface with the valve carrier plate above.

A system that can eliminate engine combustion emissions in addition to raw and fugitive methane emissions associated with a gas compressor package. The system may comprise an air system for starting and instrumentation air supply; electrically operated engine pre/post-lube pump, compressor pre-lube pump, and cooler louver actuators; compressor distance piece and pressure packing recovery system; blow-down recovery system; engine crankcase vent recovery system; a methane leak detection system; and an overall remote monitoring system.

A vehicle air compressor comprises a crankcase having a longitudinal central axis. The vehicle air compressor also comprises a head assembly including (i) a rear face that lies in a plane transverse to the longitudinal central axis of the crankcase, (ii) an air inlet port oriented in the same plane as the rear face, (iii) an air outlet port oriented in the same plane as the rear face, (iv) a coolant inlet port oriented in the same plane as the rear face, and (v) a coolant outlet port oriented in the same plane as the rear face.

Provided are a heat module for an air compressor, in which introduction of foreign substances into a stroke space in which a crankshaft and a piston assembly are accommodated is completely blocked, and leakage of noise generated from the stroke space to the outside is minimized, and an air compressor including the same. The head module for the air compressor includes a crankshaft configured to receive power from the outside so as to rotate, a piston assembly including a connecting rod coupled to the crankshaft and a piston configured to reciprocate by the connecting rod, a crank body in which the crankshaft is accommodated, a cylinder assembly which is coupled to the crank body to communicate with the crank body and in which the piston is disposed, a valve unit accommodated in the cylinder assembly and configured to be opened and closed according to the reciprocating motion of the piston, a filtration filter coupled to the cylinder assembly and configured to filter air introduced into the cylinder assembly, and a cooling fan coupled to the crankshaft and disposed on an end of the crank body to rotate by the crankshaft so that unfiltered air is introduced into the crank body.

A power end includes a monolithic core with a base having a surface configured to mount to a fluid end of the reciprocating pump and a plurality of extensions integral to the base. Each extension of the plurality of extensions includes a ring portion that defines an opening configured to receive a crankshaft of the reciprocating pump. The power end also includes a plurality of plates separate from the monolithic core. Each plate of the plurality of plates extends between a pair of adjacent of extensions of the plurality of extensions to enclose the monolithic core.

A compressor and a refrigeration device are provided. The compressor has a crankshaft, a connecting structure, and an avoidance part arranged on the connecting structure and/or the crankshaft. The avoidance part is located at a position where the connecting structure is matched with the crankshaft. The avoidance part is configured to be suitable for avoiding at least one of the connecting structure and the crankshaft. A gap between the crankshaft and the connecting structure is increased through the arrangement of the avoidance part, so that the avoidance part can avoid the crankshaft when the crankshaft is obliquely deformed.
