A method for producing a hollow body that is pressure-tight for a predetermined medium through the joining of at least two sub-bodies, which when joined form the hollow body that contains the medium in a gaseous and/or liquid state during the intended use of the hollow body; the at least two sub-bodies are integrally joined by means of an integral joining method that can be successfully performed at ambient pressure; the medium is introduced into at least one sub-cavity of at least one sub-body in a solid or partially solid state before the integral joining is performed, the medium is introduced together with a container element that contains or holds the medium in a solid or partially solid state, from which containing element the medium can escape in the liquid or gaseous state; and then the integral joining is carried out.

The invention relates to an arrangement for sealing off a piston rod, which moves substantially rectilinearly in a reciprocating manner with respect to a passage opening, of a reciprocating-piston machine, having at least two internally clamping sealing rings, which surround the piston rod and are arranged in the region of the passage opening so as to be substantially fixed with respect to a seal housing, and are mounted in the seal housing so as to be movable in a radial direction, and between at least two seal rings there is arranged a spacer ring which is arranged spaced apart from the piston rod, so as to form, together with the seal rings and the piston rod, an accumulation chamber for medium to be sealed off, for example for oil, and the spacer ring has at least one passage for discharging medium out of the accumulation chamber.

A liquid gas engine includes at least one combustion chamber, in which a liquid gas/air mixture is introduced and ignited, the liquid gas engine having an injection device which injects liquid gas via an injection nozzle. The injection nozzle opens into the combustion chamber, so that the liquid gas is injected directly into the combustion chamber. The direct injection of the liquid gas achieves ideal combustion conditions, particularly since liquid gas evaporating in the combustion chamber induces cooling which is utilized particularly under a high load. The liquid gas engine is preferably provided with an injection device which is designed as an alternating piston pump and which works on the energy accumulation principle.

A piston-ring arrangement for use in an internal combustion engine including a cylinder with a piston axially displaceable within the cylinder and at least one piston ring guided in the cylinder. The cylinder, piston and piston-ring are made of a ceramic material. The piston ring is formed of two circumferentially extending parts and is mounted in a groove in the circumferentially surface of the piston. The groove has a depth greater than the corresponding radial depth of the piston ring so that a spring element can be positioned between the base of the groove and the piston ring for biasing the piston ring radially outwardly. The spring element can be annular member with a corrugated shape or a multi-part ceramic member shaped to provide a biasing action.

The invention relates to an internal combustion motor, in particular a lift-piston motor with internal combustion and with cylinders arranged in-line, as well as with at least one rotating control element for the gas charge change processes, which is arranged between cylinder block and cylinder cover with an axis of rotation lying perpendicular to the cylinder axis and between two pivots extending rotation-axially presents a control body standing in fixed connection with the pivots, there being provided counter-surfaces in the cylinder head surrounding the control body and the pivots uniformly and each pivot being traversed by an axially extending gas channel, which goes over in each case into an elbow-shaped gas channel arranged in the control body, which channel emerges with an opening at the surface of the control body, and an arrangement being provided for the transfer of a rotary movement from the crankshaft to the control element, characterized in that the control body is constructed as a sphere, in particular as a hollow spherical body.

Internal combustion motor

A four-stroke internal combustion piston engine includes at least two cylinders disposed in axial alignment opposite on another. Each cylinder has a piston axially reciprocal therein with the pistons in the two cylinders operating with a phase shift of 180.degree.. Each piston is connected by a piston rod to the same crankshaft located between the cylinders. Each piston moves between a bottom dead center at an inner end of the cylinder adjacent the crankshaft to a top dead center at an outer end of the cylinder spaced outwardly from the crankshaft. During movement of the piston from the inner end to the outer end, fresh air or a fuel-air mixture is drawn into the cylinder through a suction system and when the piston moves in the opposite direction a transfer system conveys the fresh air or fuel-air mixture into a combustion space formed between the outer end of the cylinder and the piston. Each cylinder has its own suction system and transfer system including check valves so that the supply and flow of the fresh air or fuel-air mixture is separate for each cylinder.

In a two-stroke internal combustion engine with facing cylinders, piston rods extend from the cylinders into a central crank guide located within a crankcase. A crankpin is located within the crankcase and a sliding piece forms the bearing points between the crankpin and the crank guide. The sliding piece is made up of solid or laminated ceramic components so that the friction heat can be removed using the water from the engine cooling circuit.

Crank guide assembly for internal combustion engines, in particular

In a two-stroke internal combustion piston engine, a piston is reciprocally movable within an axially elongated cylinder. The piston has a bottom dead center position and in the region of this position, the cylinder has an exhaust opening and a number of pairs of scavenging openings. An axially extending plane within the cylinder divides the exhaust opening in half and in each pair the scavenging openings are arranged symmetrically on opposite sides of the axially extending plane. Each pair of scavenging openings is located at a different distance from the exhaust opening. The projection of the side surfaces of the pairs of scavenging openings extending in the axial direction of the cylinder each form a different angle at the point of intersection of the projections and the point of intersection is directed away from the exhaust opening. The projection of the side surfaces of the pairs of scavenging openings extending transversely of the axial direction form different angles with a plane extending perpendicularly of the axial direction of the cylinder.
