The aim of the invention is to improve the efficiency of an axial-piston motor. To this end, the axial-piston motor comprises at least one compressor cylinder, at least one working cylinder and at least one pressure line guiding the compressed fuel from the compressor cylinder to the working cylinder. A working piston comprising a working rod is provided in the working cylinder, and a compressor piston comprising a compressor rod is provided in the compressor cylinder. The axial-piston motor is characterized in that it at least one of the two rods comprises transverse stiffeners.

The invention relates to a tubular piston for a piston engine, comprising a tubular section, a collar shaped region and a ball pivot formed thereon, and an inner tube arranged in an outer tube. A cavity is at least partially formed between the outer tube and the inner tube. Said cavity is sealed from the area surrounding the hollow piston in a pressure-tight manner, by a material, especially a solder material, which is arranged in the cavity in a positively locking manner by means of heating.

A compression ignition rotating cylinder engine (CIRC), provides a design that has several distinct advantages over conventional internal combustion engines. Rotating cylinder blocks and a fixed header plate provide a more fuel-efficient engine with constant positive torque and reduced vibration.
摘要:
This invention relates to internal combustion engines with cylinders arranged parallel to the main shaft and where reciprocating movements of the pistons are converted to rotation by means of a Z-crank mechanism and motion converter, or conversely to systems such as pumps and compressors wherein rotation of the Z-crank and motion converter produces reciprocating motions of the pistons. The motion converter is prevented from rotation by a reaction control shaft or by a gear train. Connecting rods are prevented from rotating about their long axes. Double-ended configurations can be either opposed cylinder or opposed piston, and may include multiple pairs of pistons with each pair in a common cylinder. The Z-crank may be moved axially for the purpose of varying the compression ratio. Variation of the compression ratio is controlled by an engine control unit and is adjusted to optimize engine performance under varying loads and other conditions.

The invention relates to a method for the production of a ball jointed connection between a guide shoe (10) and a cylinder piston (1) of a piston machine. A spherical cap-shaped recess (2) is first of all formed on the cylinder piston (1) and/or the guide shoe (10), whereby the recess (2) is undercut in such a way that the spherical cap-shaped recess (2) comprises a solid angle area (&agr;) of over 180°, and the diameter (D) in the region of the equator plane (5) is greater than the diameter (d) of the recess (2). Furthermore, a spherical head (11) is formed on the corresponding counterpart, that is the guide shoe (10) and/or the cylinder piston (1). In accordance with a first version of the invention, the spherical head (11) is pushed into the spherical cap-shaped recess (2) in such a way that the edge area (6) surrounding the spherical cap-shaped recess (2) is elastically deformed when the spherical head (11) is pushed in, and the surrounding edge area (6) grips behind the spherical head (11). Alternatively, the spherical head (11) has a flattening (20) which is plastically deformed after introduction of the spherical head (11) into the recess (2).
摘要:
An improved method of manufacturing a piston is provided. The piston includes a substantially cylindrical member having a first end and a second end. The cylindrical member includes an open cavity extending axially from the second end to adjacent the first end such that the second end has an inner annular surface defined by an inner diameter. The piston further includes a disk having a radially outer surface defined by an outer diameter fixedly secured to the second end of the cylindrical member. The outer diameter of the disk is substantially equal to the inner diameter of the inner annular surface of the second end of the cylindrical member. A circumferentially extending recessed area for receiving particles produced while fixedly securing the disk to the second end of the cylindrical member is provided on either the radially outer surface of the disk or the inner annular surface of the second end of the cylindrical member.
