An air compressor contains: a body, a cylinder, a motor, and a transmission mechanism. The body includes multiple positioning orifices which are a first positioning orifice and a second positioning orifice. The cylinder is connected on the body and communicates with an air storage holder. The motor is fixed on the body, a small gear is received in the first positioning orifice, and a connection seat of the motor is accommodated in the first orifice. The transmission mechanism actuates the piston to move in the cylinder reciprocately so as to produce compressed airs. The motor further includes multiple fixing portions extending from a head edge of the casing thereof and configured to engage with the body, thus fixing the motor on the body securely without using any screws.

An air compressor is received in an accommodation box and contains a body, a cylinder, a motor, and a transmission mechanism. The body includes a first positioning orifice and a second positioning orifice. The cylinder is connected on the body and communicates with an air storage holder. The motor is fixed on the body, a small gear is received in the first positioning orifice, and a connection seat is accommodated in the first orifice. The transmission mechanism actuates a piston to move in the cylinder reciprocately so as to produce compressed airs. The motor includes at least one locking extension for engaging the motor with the body, hence the motor is fixed on the body securely without using any screws.

The device consists of two separate parts: a stationary unit (12) which contains a motor (16) and vacuum pump (14), and a mobile head (20) with a power-supply switch for the motor and an aspirating nozzle designed to fit over the valve (32) in the lid of an airtight container (28, 30). The mobile head connects to the stationary unit with two flexible coaxial spiral cords, consisting of a hose (22) linking the vacuum pump and aspirating nozzle, and a power cord (36) linking the switch to the electrical motor. Both lines can easily be stretched together from the storage position, in which the mobile head sits on the stationary unit, to active mode, in which the suction effect keeps the mobile head coupled to the container.

The invention relates to a refrigerant compressor, comprising a compressor housing (1) that can be hermetically capsuled, and a compressor-motor unit (4) arranged in the housing interior (3) of the compressor housing (1), which is elastically mounted on an inner side of the compressor housing (1) by way of at least one spring element (5), wherein at least one damping element (9) made of an elastomer is provided, in order to damp the transmission of vibrations caused by the compressor-motor unit (4) to the compressor housing (1). The at least one damping element (9) is made of an elastomer that is softer compared to polyamide (PA), polybutylene terephthalate (PBT), ethylene chlorotrifluoroethylene (ECTFE).

The present invention reveals an alternative compressor head arrangement capable of eliminating the occurrence of friction wear in the bending areas of the operation valves. For this, an interface blade arranged between the valve blade and the stop blade is used, so that the interface between the static end of the operation valve of the valve blade and the valve stop of the stop blade is fully carried out by the interface blade.

A suspension system for a compressor assembly is provided. The compressor assembly includes at least one cylinder, at least one inlet fluidly connected with the at least one cylinder, an outlet fluidly connected with the at least one cylinder, and a motor housing. The suspension system includes a suspension member and a frame member. The suspension member includes a first fluid conduit connected with the coupling portion and including a first fluid terminal. The first fluid conduit is disposed in fluid communication with one of the outlet and the at least one inlet of the compressor assembly. The frame member includes a base portion, a first support portion, and a second support portion. A first mounting region is formed between the first support portion and the first fluid terminal. The first mounting region defines a first volume that at least partially encloses the first fluid terminal.

Disclosed is an air compressing apparatus with a dry-air internal-emission trap unit, and more specifically, to an air compressing apparatus with a dry-air internal-emission trap unit which solves various problems arising due to venting and improves an on-site environment where compressed air is used by guiding the venting to an inside of a system for compressing air rather than guiding the venting in the system for compressing air to the outside (atmosphere), and which maximizes energy efficiency and obtains a virtuous circle of energy by enabling compressed air that is discarded to be reused.

A reciprocating air compressor arrangement includes a crank that drives a connecting rod and a piston within a cylinder. The connecting rod has a first end and a second end. The first end of the connecting rod is connected to the crank and the second end of the connecting rod is connected to the piston, with the crank provided to actuate the piston in a reciprocating motion within and relative to the cylinder so as to compress air within the cylinder. The reciprocating air compressor arrangement has a one-way flapper inlet valve allowing air to enter the cylinder, and a one-way outlet valve allowing compressed air to exit the cylinder. The inlet valve is biased to a partially open position.
