In English it's called a helical compressor, also a screw compressor. Try the ref. 1 page for a starter (illustrations are in separate links at the bottom of the page). Looking at the 2nd illustration, apparently a seal is formed between the lower side of the roller and the cylinder it rotates in, forming multiple closed chambers along the long axis of the roller and spiral blade. Rotation moves these chambers along the axis, and they get progressively smaller as they move due to the decreasing pitch of the blade. Ref. 2 describes other versions that use two or more meshed screws.

Zeagle regulators.\n\nConsistently rated a top performer and top pick by Scuba Diving magazine's comparison tests, great factory support with free annual service parts if you buy from an authorized dealer, and dealers such as ScubaToys will match prices from grey market dealers.\n\nOf the Zeagle regulators, I prefer the DS-Vs.  Simple design, environmentally sealed, highly regarded by tech divers (similar to Apeks DS4).

Air systems, regardless of compressor design or capacity, can operate more efficiently and economically through the proper selection and optimization of the control system used with the compressor unit.Compressor control systems have long had the ability to monitor and adjust basic air compressor functions, associated with monitoring, loading, unloading and throttling. Now, some systems provide additional features such as trend analysis, predictive maintenance schedules as well as remote monitoring and operations.compressor control systems function on a demand cycle. If the demand for compressed air is steady and does not fluctuate, compressor controls simply match the capacity to the system demand. One basic form of compressor flow control is called inlet throttling, or inlet unloading. \nReducing the air flow is achieved by reducing the inlet opening through which the air enters the compressor. This, in turn, matches the compressor output to the system demand. Because system pressure acts a s a demand indicator, throttling is usually controlled by system pressure. However, most air systems are more complex and demand is more variable than the one described. \nProcesses with complicated and varying demand cycles, which can include several compressors of different sizes and configurations to maintain system pressure, require a more sophisticated control system. The most common of these systems is the electro-pneumatic control system. \nMore than 70 percent of all existing air compressors utilize electro-pneumatic control systems. These compressors feature electric and mechanically controlled devices -- such as pressure switches, solenoid valves and metering pins -- that adjust the loading and unloading through the use of an inlet throttle and/or a bypass valve. These control systems typically rely on mechanical pressure switches to monitor the compressor's proper discharge pressure. In addition, electro-pneumatic systems typically feature a series of mechanical trip switches that will discontinue compressor operation when pressures or temperatures reach critical levels.The electro-pneumatic action is a control system for pipe organs whereby air pressure, controlled by an electric current and operated by the keys of an organ console, opens and closes valves within wind chests, allowing the pipes to speak. This system also allows the console to be physically detached from the organ itself. The only connection was via an electrical cable from the console to the relay, with some early organ consoles utilizing a separate wind supply to operate combination pistons.\nAlthough early experiments with Barker lever, tubular-pneumatic and electro-pneumatic actions date as far back as the 1850s, credit for a feasible design is generally given to the English organist and inventor, Robert Hope-Jones. He overcame the difficulties inherent in earlier designs by including a rotating centrifugal air blower and replacing banks of batteries with a DC generator, which provided electrical power to the organ and drove the blower. This allowed the construction of new pipe organs without any physical linkages whatsoever. Previous organs all used tracker action, which requires a mechanical linkage between the console and the organ.\nThe basic operation of the system is as follows: when the organist selects a stop and depresses a key, an electric circuit is completed, causing a low-voltage current to flow from depressed key, through the stop-tab switch, and on through the cable to the electro-pneumatic relay. The relay interprets the command from the console and sends an electric current to the appropriate solenoid. The solenoid is energized, causing the pipe valve connected to it to open, which emits compressed air into the pipe, allowing the pipe to speak.\nThe system was an unqualified success. However, the single, most significant drawback to the system was in the massive amount of wiring required for operation. With each stop tab and key being w

It is not clear if you mean a mechanical design pressure of 6 bar or a performance limit due to configuration of 6 bar. If it is a mechanical design limitation there is little you can do unless you wish to take the risk of a casing or other failure and the danger that can bring. \n\nI assume this is not a positive displacement compressor because most positive displacement compressors will produce any pressure up to the limit of the driver or the failure pressure of some pressure component. That is the reason for safety relief valves on all positive displacement compressors.\n\nCentrifugal compressors can have their discharge pressure raised my either a larger impeller or a higher speed. You might also raise the suction pressure if that is a option. On raising the speed you must be careful that you do not run into a critical speed or a torsional vibration problems. \n\nHave you talked with the manufacturer? Sometimes they can provide help.

Most refineries produce fuels other than petrol diesel and CNG. ATK- avaition turbine kero for aircrafts, DPK - dual purpose kero for domestic use and also used by some jet engines. LNG - liquefied natural gas is produced by LNG comapnies. Bidiesel is produced by a comapny in association with ONE of the motor gaints of America - GM or Ford (I'm not too sure now)

These are components (for example) of steam power plants (stationary and marine).  Engineering Handbooks (Marks' Mechanial Engineers' Handbook, etc.) should provide definitions and perhaps examples of steam, air and water pressure reducers and steam desuperheaters.  Visit any large library and ask at the Reference Desk for technical handbooks (or any other books re' steam power plants).\n\nEngineers would contact manufacturers for detailed product information before specifying equipment.\n\nGood luck.
