Self acting compressed air engine - has reciprocating inner cylinders compressing air inside stationary outer cylinders with four stroke action

The engine has four fixed cylinders. In place of a piston each has an inner cylinder which reciprocates within it. The bottom of each reciprocating inner cylinder is joined by a connecting rod to a crankshaft, the four cranks being angularly displaced from each other. Each inner cylinder has a floating piston within it which is moved by air pressure. The fixed cylinders have valve openings through which an initial charge of compressed air is introduced. This starts the engine and then on each stroke two cylinders provide the driving force while the other two are compressing a fresh charge of air. The engine thus continues to run without further supplies of fuel or energy.

SUPPORT WITH A SUPPORT SYSTEM FOR PISTON ENGINE GUIDE SLIDES

Vapour motor for use in solar heating systems - incorporating a collection and return system for fluid leaks and having sliding surfaces pref. of PTFE

The fuid circulates in a closed circuit between the solar heater, where it is vapourised, and a condenser, where it is liquefied, passing through a piston and cylinder motor where part of its thermal energy is transformed to mechanical energy to drive the pump. The surfaces of the motor which are in sliding contact are pref. made of PTFE to eliminate the necessity of lubrication. The motor cylinder is provided with a double gland packing through which the piston shaft moves, the space between teh packings forming a fluid collection chamber from which the fluid is returned to the condenser. The lubrication of the motor parts in contact with the motor fluid is avoided, so the mixing of the fluid and the lubricant which would lead to a loss in efficiency and possible motor trouble is avoided. The collection and return to the circuit of fluid eliminates the necessary for replenishing the motor fluid. This makes the motor suitable for use in areas such as semi-desert areas where constant fluid replenishing is impracticable.

Patent FR2358544B1

Member for regulating the flowthrough quantity of a pressure medium

The member is to make it possible to reduce automatically the speed of a compressed-air engine when the engine is not loaded (idle running). In the housing (5), a movable plate (4) is guided by diaphragms (3). In the working position illustrated, the air passes from the inlet (1) via bores in the plate (4) to the outlet (2). In the case of an increasing flowthrough quantity (reduction of engine load), the pressure difference rises above the plate (4) so that the latter snaps over into the idle-running position, in which the bores are closed by a sealing ring (6) except for an adjustable idle-running passage (7). On loading of the engine, the plate (4) snaps back into the working position. The speed of the unloaded engine is greatly reduced by the member, which increases safety in the driving of grinding discs. Moreover, air consumption and noise level in idle running are low. <IMAGE>

Detecting end of stroke in a hydraulic motor

It is challenging to detect end of stroke for hydraulically actuated, reciprocating piston pumps for a variety of reasons. When the pump pressurizes a process fluid to a 10 relatively low pressure the magnitude of hydraulic fluid pressure is not as distinct compared to the magnitude of a pressure drop across a shuttle valve employed to detect end of stroke, which makes detecting the end of stroke event difficult. A method is disclosed for detecting end of a piston stroke in a hydraulic motor comprising a reciprocating piston with a shuttle valve. The method comprises 1 detecting end of piston stroke when a magnitude of a rate of change of hydraulic fluid pressure is substantially greater than a magnitude of a mean rate of change of hydraulic fluid pressure over said piston stroke; and noise in a hydraulic fluid pressure signal is substantially negligible.
