Abstract: In a reciprocating internal combustion engine with a mechanically-driven charger (20), the number and disposition of cylinders of the internal combustion engine is such that free forces/moments of inertia are still provided. At least one shaft of the mechanical charger is disposed parallel to the crankshaft of the reciprocating internal combustion engine. The mechanical charger (20) is driven in an angle-synchronous manner with the crankshaft (32) of the reciprocating internal combustion engine. The transmission ratio between the charger and the crankshaft is in whole numbers. The charger (20) has a balancing centrifugal weight on at least one of its shafts which during operation counteracts the free forces of inertia of the reciprocating internal combustion engine for the purpose of a low-vibration or vibration-free operation of the internal combustion engine.

Abstract: A positive-displacement machine for compressible media has a positive displacement body that is retained on a disk-like rotor, which is eccentrically drivable relative to the housing, in such a manner that each of its points executes a circular motion during operation. To that end, an eccentric disk is disposed on a drive shaft, and the rotor is supported on this disk by means of an oil-lubricated bearing. The lubricating oil is delivered and removed to and from the side remote from the drive side of the drive shaft, and the separation of the oil inflow from the oil return flow is effected in the housing by a slide bearing which has one oil chamber each on both ends. The separation of the oil streams is effected by an indentation that does not extend over the entire length of the slide bearing. Through this indentation, the slide bearing is likewise supplied with oil. The indentation connects the oil inflow bore in the housing with the oil chamber.

Abstract: In a positive-displacement device for compressible media with a helically-shaped conveying chamber disposed in a stationary housing, a helically-shaped positive-displacement body is associated with the conveying chamber. The body is maintained on a disk-shaped rotor which can be eccentrically driven in relation to the housing in such a way that during operation, each one of its points performs a circular movement which is limited by the circumferential walls of the conveying chamber. The front faces of the positive-displacement body adjoining one lateral wall of the conveying chamber are provided with a groove into which a sealing strip, consisting of a resilient material which is capable of gliding, is inserted. The groove has at least partially a meander-like extent.

Abstract: A displacement machine for compressible mediums has several spiral-shaped conveying spaces (11a, 11b), which are disposed in a stationary housing lead from an inlet (12a, 12b), which lies radially on the outside, to an outlet (13), which lies radially on the inside. A displacement body, which is assigned to the conveying spaces has a disk (2) with spiral-shaped strips (3a, 3b) arranged perpendicularly on both sides. This displacement body, driven off-centered, is made of a magnesium alloy. During service, each of its points effects a circular movement defined by the circumferential walls of the conveying space. The ribs (45, 46) bordering the conveying spaces (11a, 11b) in the housing are made as one piece with the housing and the entire housing is made of the same or similar magnesium-based alloy as the displacement body (2, 3, 4, 5).

Abstract: A rotating spiral pump comprises a housing in which two displacement disks are rotatably disposed. The two displacement disks are provided on one side with ribs that extend in spiral fashion and interlock for the purpose of forming pumping chambers, and seal against the opposite displacement disk with their free face ends. The spirally extending ribs are embodied in several steps. The plurality of steps are spatially separated from each other by the formation of an space, and the radially outer step has at least twice as many pumping chambers as the radially inner step. Cooling means in the form of cooling ribs are preferably provided in the space, between the outlet of the radially outer step and the inlet of the radially inner step.

Abstract: In an eccentric gear in which the gear rim of a first orbiting cog wheel is in engagement with the gear rim of a second rotating cog wheel, the two gear rims are offset from each other by an eccentricity. The second cog wheel is fixed to a driven shaft seated in a fixed housing. At least three eccentric shafts, which are evenly spaced about the circumference of the cog wheel, are provided for guiding the orbiting cog wheel, the eccentrics of each shaft being seated in respective bores of the orbiting cog wheel. One of the three eccentric shafts extends through the housing wall on one side and is formed as the drive shaft. The three eccentric shafts are coupled via a slider orbiting with an eccentricity which is considerably greater compared with the drive eccentricity.

Abstract: A displacement machine for compressible mediums exhibits several spiral-shaped conveying spaces, which are disposed in a stationary housing and which span a circumferential angle of approximately 360.degree.. The spiral-shaped displacement bodies, which are assigned to the conveying spaces and which span a circumferential angle of approximately 360.degree., are held in such a manner on a disk-shaped rotor, driven off-centered with respect to the housing, that during service each of their points effects a circular movement defined by the circumferential walls of the conveying spaces. The predominant reach of both the spirals of the conveying spaces and the displacement bodies extends with a first curvature and their exit-sided end exhibits over an angular range (.alpha.) of 45.degree. a second curvature that is clearly smaller.

Abstract: A displacement machine for compressible mediums exhibits several spiral-shaped convoying spaces (11a, 11b), which are disposed in a stationary housing (7a, 7b). A displacement body (1-4) is assigned to the conveying spaces and is held in such a manner on a disk-shaped rotor (1) that can be driven eccentrically relative to the housing that during service each of its points effects a circular movement defined by the circumferential walls of the conveying spaces. To this end an eccentric disk (23), on which the rotor (1) is mounted by means of an oil-lubricated mounting, is disposed on the drive shaft (24). A sliding bearing (22) is provided on the rotating eccentric disk (23) for the orbiting rotor (1). The oil is fed in and drawn off by way of a borehole (31) in the eccentric disk. Passages are disposed within the eccentric disk to feed oil without air into the sliding bearing gap.

Abstract: A displacement machine for compressible media includes a stationary housing, and a plurality of disks mounted for eccentric movement within the housing. Each of the disks has two symmetrically disposed spiral displacement bodies that are offset from one another by substantially 180.degree. mounted on at least one side thereof so that the spiral displacement bodies move in an orbital fashion within the housing during operation. The disks are positioned with respect to one another such that each of the spiral displacement bodies intermeshes with another spiral distribution body to define pairs of cooperating spiral displacement bodies. The spiral displacement bodies have a curvature that is dimensioned such that opposed surfaces of cooperating spiral displacement bodies substantially contact one another at at least one sealing line that progresses continuously during operation.

Abstract: A rotating sprial charger for compressible media is disclosed having a housing in which two symmetrically constructed displacer disks are located and rotated by drive elements. The two displacer disks are provided on one side with helical ribs. To form a conveying space, the ribs engage each other and seal with their free frontal sides against the opposing displacer disk. To increase the strength of the ribs, a reinforcement is provided on the outer periphery of the ribs. The reinforcement is located on the outer wall of the rib and extends over the entire axial length of the ribs. The reinforcement also extends in the peripheral direction from the end of each rib on the inlet side to the end on the inlet side of the rib following in the peripheral direction.

Abstract: A rotating helical charger for compressible media consists essentially of a housing (1), in which two symmetrically constructed displacement disk (6, 7) are rotated by drive elements (18-23). The two displacement disks are equipped on one side with helical ribs (14). To form a conveying space (15), the ribs engage each other and seal with their free frontal sides (24) against the opposing displacement disk. To maintain the sealing effect, a pressure chamber (26) is provided, which communicates with the outlet (16) of the charger and may be acted upon by an axially displaceable annular disk (28), actively connected with an axially movable displacement disk (6). The pressure chamber (26) may be connected by means of a valve (32) with the atmosphere.

Abstract: An automatic lubricant metering device consists essentially of a housing (4), from inside of which a piston (5) is conveying a lubricant (15) through a feeder line (12) to the lubricating location (2) of a revolving shaft (1). The automatic feature consists of that the spring-loaded piston (5) is connected with a pin (6) made of an abradable material. The advance of the piston (5) is a function of the abrasion of the pin (6) on the appropriately roughened surface of the shaft. The lubricant is contained in a compressible bellows (11) equipped with a feeder line (12) to the lubricating location (2). The feed to the lubricating location is conducted in the area of the shaft through a pipe (13) located preferably without contact in a center bore (14) of the shaft. The outlet of this pipe opens into a radial bore (16) connected with the lubricating location (16).
