Method for operating a compressor having at least two cylinders, and device for implementing the method

A compressor 1 having at least two cylinders 3, 4 is operated according to conventional methods in such a manner that in accordance with the cycles of the other cylinder heads each cylinder draws in the medium to be compressed, compresses it and retains it up to the UDC of the piston 5, 6. In order to reduce the emission of noise in the driving gear 10 of the compressor 1 and to increase the compression ratio of a compressor of this type, it is provided that after ejection of the compressed medium from the one cylinder 3 the compressed residual medium remaining in the said cylinder 3 is expanded approximately at the UDC position of its piston 5 into the other cylinder 4 whose piston 6 is approximately at the EBC position. A device for implementing this method comprises a compressor having at least two cylinders 3, 4 which can be connected to one another by means of a transfer port 2 to be opened briefly.

Improvements in Regulating or Governing Devices for Air Compressors.

... 19,018. Broom, H. S., and Broom & Wade. Aug. 24. Regulating and controlling compression.- Air-pumps are provided with controlling-means of the type in which a spring-controlled valve is connected with the receiver so that air passing the valve when the pressure rises to a predetermined limit is conducted to a cylinder, the piston of which holds the suction valve open until the pressure falls. This means is described in connexion with a multi-cylinder compressor in which each cylinder has a piston cylinder connected to the spring valve casing and controlling the corresponding inlet valve. Air from the common pump delivery pipe f is led to the top of a valve casing 2, Fig. 3. When the pressure rises above the limiting value, a valve 5 in the casing is depressed, and air passes by a notch 6 into the casing. A leak valve 8 is simultaneously depressed against the action of an adjustable spring 18 and toggle stays 22 shown, and closes the casing to the atmosphere, allowing the air under pressure ...

FLEXIBLE SUPPLY GAS ROUTING FOR GAS COMPRESSORS

Most multistage compressors specify a maximum inlet pressure that may be supplied to the compressor to stay within designed limits. If the supply gas to be compressed is at a higher pressure than the specified maximum inlet pressure, then its pressure must be reduced before connecting it to the compressor. This pressure reduction is inefficient. The present invention avoids reducing the inlet pressure by routing the supply gas directly to the appropriate compression stage depending on its inlet pressure such that the compressor loads are still within the specified limits of the equipment.

Improved integrated oil-less high capacity air pump

An air cooled compressor is provided with a centrifugal type fan mounted on one end of a motor shaft. Cooling air is drawn through a shroud for bearing eccentric and connecting rod cooling. A shroud also directs the cooling air drawn and delivered by the fan, over the external surfaces of thinned cylinders and cylinder heads. The cooling air flowing over the thinned cylinder heads also functions to cool the intake air which assists in reducing the temperature experience within the compression chambers of the compressor. A pair of oppositely disposed openings are formed in the wall of each cylinder, which openings register with a wrist-pin that connects a connecting rod to a reciprocating piston when the piston is in the lowermost portion of a stroke within the cylinder. This construction allows the cooling air to flow through the hollow wrist-pin for cooling purposes. The cylinders are mounted to the motor frame by first securing a crankcase base to the frame, after which four equally spaced ...

Crankcase sealing apparatus

A compact 180° opposed piston pump/compressor minimizes axial spacing between its pistons on the drive shaft and thereby reduces the shaking couple and noise from reciprocation. Each piston has its own eccentric element press-fit into the connecting rods so as not to occupy space between the pistons. The shaking couple can be further reduced for pistons of different masses by selecting the mass of the cup retainers to compensate for the difference in overall piston masses. The pump also includes an improved cylinder sealing arrangement having a circumferential groove in an angled surface at the end of the cylinder. The pump also has a special cover and seal for closing the open neck of the pump crankcase and an improved multi-lobed valve stop. The pump further uses tubular transfer members for transferring intake and/or exhaust air into the crankcase and/or between valve heads.
