DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention refers to a two-stroke, axial pistons engine, with pressurized scavenging chamber, which may be used to drive both transport means and power plants.
BACKGROUND OF THE INVENTION
Multicylinder internal combustion engines with axial pistons are known, in which the pistons are placed two by two, opposed, in the same cylinder, the guiding rail which prevents the oscillator rotation being fixed, the gaseous exchange being achieved through scavenging apertures, which make a direct connection between the cylinder and the precompression space which may be achieved by the compressor near the engine. The shortcoming of these engines is that they do not solve the problem of a total operational freedom of the connecting rod and of the oscillator guide. At the same time, they do not provide an adequate gaseous exchange which would result in a high volumetric efficiency.
SUMMARY OF THE INVENTION
According to the present invention, the two-stroke axial engine does not have any of the above-mentioned shortcomings, because in order to ensure an optimization of the gaseous exchange, which should account for a high volumetric efficiency, and a free movement of the connecting rod-oscillator system, the intake of the fresh mixture is effected directly in a scavenging chamber through an inlet aperture placed in the lower part of the cylinder and actuated by the primary shaft, which, with this end in view, has a longitudinal groove, the fresh mixture actuated by the piston being then forced from the scavenging chamber by means of scavenging apertures into a combustion chamber. Between the scavenging chamber and the crankcase interior there is mounted a separator formed by a case fixed on the cylinder block, a first spherical bushing installed between the case and a mobile connection, a second spherical bushing mounted between the mobile connection and the connecting rod, between the first spherical bushing and the mobile connection, and between the second spherical bushing and the case being mounted on a ring-shaped gasket. In order to prevent oscillator lock, a fork is mounted in the body of the oscillator, having relative rotating possibilities, and the guiding rail on which the fork slides is assembled in the cylinder block in two bearings, which allows it to rotate.
BRIEF DESCRIPTION OF THE DRAWING
The above and other objects, features and advantages of the invention will become more readily apparent from the following description, reference being made to the accompanying drawing, in which:
FIG. 1 is an axial sectional view of the engine according to the invention;
FIG. 2 is a sectional view taken along line II--II of FIG. 1;
FIG. 3 is a half sectional view taken along line III--III of FIG. 1, the other half being mirror-identical thereto; and
FIG. 4 is a half sectional view taken along line IV--IV of FIG. 1, the other half being mirror-identical thereto.
SPECIFIC DESCRIPTION
The two-stroke axial engine of the present invention is made up, essentially, of a primary shaft A carrying a cooling fan 32 at one end and an output gear 33 at the other end and mounted parallel to the engine cylinders 1, within each of which are two working pistons 2, so that they form between them a combustion chamber a, the pistons being connected by means of a spherical articulation b with the connecting rods B, which, oscillating during the operation, acts to oscillate a separator C which divides the cylinder from the crankcase 29 in an already known manner.
At the other end, the connecting rods B are also connected by means of a spherical articulation c to an oscillator D.
The axial engine also includes a subassembly E meant to guide oscillator movement. The primary shaft A, whose role is to provide the control of the gaseous exchange and to transmit the torque outwards, is made up of four sections 3, 4, 5 and 6 which are assembled and journaled by means of end bearings 7 and tightening screws 8. Two longitudinal grooves d are provided in the central section 4 of the primary shaft on the same gener
