Embodiment Construction

[0093] figure 1 The active chamber engine according to the invention is shown, on which the engine cylinder 1 can be seen, in which the piston 2 slides, connected via the connecting rod 3 to the journal 4 of the crankshaft 5 .

[0094] The volume of the cylinder 1 of the engine according to the invention swept by the piston 2 is divided into two parts along the imaginary line DD' (which corresponds to the dividing plane perpendicular to the axis of the cylinder): a first part, which constitutes the active chamber CA, thus The movable chamber is built into the cylinder; and the second part, which constitutes the expansion chamber CD.

[0095] The engine cylinder 1 is covered by an upper cylinder head 6, the upper cylinder head 6 includes an intake duct 7 and an exhaust duct 8, and associated closing parts for closing these ducts, here the closing parts are intake valve 9 and exhaust valve respectively. Gas valve 10.

[0096] The intake line is connected to a working vessel 11...

Abstract

The invention relates to an engine with an active chamber, comprising at least one piston (2) mounted in a cylinder (1) in a sliding manner and driving a crankshaft (5) by means of a slider-crank device (3, 4) and operating according to a four-phase thermodynamic cycle comprising: an isothermal expansion without work; a transfer - slight so-called quasi-isothermal expansion with work; a polytropic expansion with work; and an exhaust at ambient pressure, preferentially supplied by compressed air contained in a high-pressure storage tank (12), through a buffer capacity, called a working capacity (11), which is expanded at an average pressure, called a working pressure, in a working capacity (11), preferentially through a dynamic pressure-reducing device (13), characterised in that the active chamber (CA) is included in the engine cylinder, the cylinder volume (1) being swept by the piston and divided into two separate parts, a first part forming the active chamber (CA) and a second part forming the expansion chamber (CD).

Description

technical field [0001] The present invention relates to an engine operating in particular with compressed air or any other gas, using a chamber called a "moving chamber". Background technique [0002] The inventors have filed numerous patents relating to electric motor drives and devices therefor using gases, and more particularly compressed air, for completely clean operation in urban and suburban environments. [0003] The inventors have notably filed the International Patent Application WO-A1-03 / 036088, the content of which is referred to by reference, for an additional compressed air injected electric compressor operating on single and multiple energy sources - electric AC generator set. [0004] In these types of engines that run on compressed air, including compressed air accumulators, it is necessary to use compressed air stored in the accumulator at extremely high pressure, but whose pressure decreases as the accumulator discharges, for use in one or more engines B...
