Abstract:
A controlled sequence of explosions of calculated amounts of exploding materials inside an explosion chamber, efficiently transfers a quantity of motion between a massive hammer obstructing the explosion chamber and a lighter dancer placed inside a compression chamber of an inert and non¬ flammable gas. A one-way valve communicates the compression chamber with a structurally strong tank, allowing the gas to be conveyed from the chamber to the tank. The initial speed of the dancer is gradually damped by the compression of gas inside the chamber down to zero, at steady state utilization, before impact with the one-way valve, opened by pressure generated in the chamber and immediately closed. Withdrawal of small amounts of gas at very high pressure from the tank by pressure reducers and its subsequent expansion in contact with a mechanical actuator, such as a turbine spliced to the shaft of an alternator, means that a large amount of useful work at very high efficiency can be obtained.
Abstract:
An object of the present invention is to provide a method and a system for implementing the method so as to alleviate the disadvantages of a reciprocating combustion engine and gas turbine when generating power. The invention is based on the idea of arranging a multifunction valve inside a combustion chamber to create more favourable conditions for combustion process. The multifunction valve may act as an output valve, but it can also provide additional final compression to contents of the compression chamber and it may even capture part of energy released in a combustion process.
Abstract:
A free-piston engine has a cylinder (503) and a pair of opposed pistons (502) reciprocating in the cylinder, each piston having both a hydraulic bounce function using a hydraulic accumulator (408), and a pneumatic bounce chamber (508), (509). Each piston further has a hydraulic output arrangement (603), wherein both the hydraulic bounce accumulator 408 and the hydraulic output are supplied by a single two-function hydraulic pump (507). This pump (507) comprises a pair of high-pressure hydraulic pistons (603) compressing fluid for power output of the engine and a pair of bounce pistons (602), the piston pairs being configured in a diametrically opposed arrangement to minimise imbalance. The use of both pneumatic and hydraulic bounce ensures on the one hand a very high return force, and consequently a rapid acceleration of the pistons, at the end of the expansion stroke, and on the other hand a continuance towards the end of the compression stroke. Meanwhile the two-function pumps (507) ensure that the hydraulic bounce can be controlled independently of the hydraulic output of the engine. The engine is particularly suitable for use in a turbine engine, operating as it does with a compression ratio of about 55:1, which helps to give rise to high efficiencies.
Abstract:
An internal combustion engine wherein a thermo potential heat flow in combustion is maximized by providing a feedback of an optimized amount of thermo potential heat flow that is modulated in the exhaust media, into the air intake, and a method of providing feedback comprises producing a shock wave of pulse of exhaust media and pulse of intake air on the opposite side of a high temperature shock tube thereby transferring the thermo potential heat energy flow from the exhaust media to the air intake.

The invention relates to an energy conversion system which comprises at least one compressor (14) and a turbine (16) having a turbine shaft which turbine is connected to the compressor by means of compressed gas. The aim of the invention is to provide an energy conversion system that is compact and light-weight, and universally usable for land-, water- and aircraft. The system should have a positive energy balance, especially a low specific fuel consumption. For this purpose, the compressor (14) is the pre-compressor of at least one free-piston engine (18) which has at least one piston (20) that can be reciprocated in a cylinder compartment and divides the same up into two combustion chambers (36, 38) and is connected to the turbine (16) by means of compressed gas.
