Abstract

System to Control the Reciprocating Frequency of a Double Acting Piston in a Cylinder The invention relates to a system to control the reciprocating frequency of a double acting piston in a cylinder. With this system variable constant reciprocation is achievable by attaching a double acting air compressor to the main engine shaft. Pressurized air, is fed into the air spring chamber on both sides of the piston. By increasing the pressure in the compression chamber above the atmospheric pressure, a considerable increase in the period of reciprocation can be achieved. By varying the applied pressure, a range of speeds can be achieved to suit numerous requirements.

Description

Editorial Note 2014100356 There are 2 pages of description Unique Power Solutions Pty Ltd Unit 46. 129 North Road. Woodridge Queensland 4114 An almost totally "2reen" system with the ability to control the reciprocating! frequency of a double acting piston in a cylinder either as a stand alone air system or as a double system using air and recycled gas that is contained within a closed loop system Mechanical expanders normally single expanders are used to achieve a constant period of reciprocation. By attaching a piston air spring to the main working piston, usually this air spring is pressurized by the atmosphere and sets the period of reciprocation obtained. The period of reciprocation is controlled by the elastic tension of the air spring. However with this system variable constant reciprocation is achievable. If the air spring pressure is increased, the period of reciprocation can be increased considerably. This is achieved by attaching a double-acting air compressor to the main engine shaft. Pressurized air, is fed into the air spring chamber on both sides of the piston. By increasing the pressure in the compression chamber, above the atmospheric pressure, a considerable increase in the period of reciprocation can be achieved. By varying the applied pressure, a range of speeds can be achieved to suit numerous requirements. By integrating a second similar compressor using gas instead of air, far greater power can be achieved. This gas is in an enclosed loop and is not emitted into the atmosphere. The attached drawing will give a clear understanding of how the machine works. The cut out figures shows a side elevation of the complete machine, from a partly diagonal overhead view. These include as essential parts, a work piston attached by a shaft to a Double Acting Air Spring. The work-performing piston has two inlet and outlet slots a certain distance from each other. The piston reciprocates compressed air and/or recycled gas is fed into the piston grooves alternately. The compressed air and/or gas is fed through the piston by means of tubes or holes in the direction that the piston is travelling, which causes the piston to be fired back in the opposite direction. As the piston travels down the cylinder, at a certain predetermined point it exposes the exhaust port, which releases the expanded air and/or recycled gas. The period of reciprocation, is in the main, determined by the elastic tension of the air spring combined with the reciprocating weight or mass. As an example, the machine may be reciprocating at 30 cycles per second, but it is required that the machine operate at 50 cycles per second, so that if a magnetic conductor was attached to the reciprocating shaft and was surrounded by a coil or solenoid, 50 cycle AC electricity can be produced which is suitable for commercial and domestic applications requiring electricity. To achieve a frequency increase, a small-applied pressure, above the atmospheric pressure, for example, 10 psi will increase the period of reciprocation or frequency. Another major benefit of this simple machine is that the cold expanded air of typical exhaust temperatures can easily be lowered to -50 Degrees C or colder, this can obviously be used for refrigeration or air conditioning purposes, or for cryogenic applications. These are valuable applications, As the benefit of AC power in either single or three phase and not only DC power.
