A rotary four-cycle internal combustion engine having an expansible combustion chamber defined by three identical rotors of generally triangular cross-sectional shape journalled for cooperative rotation about parallel axis and so arranged in peripheral line contact with one another as to sequentially expand and contract the combustion chamber as the rotors rotate in unison as controlled by gearing. The rotors are journalled within a cylindrical housing structure comprising inner opposed end wall...

A rotary turbine employs rotors that are rotated primarily by the frictional forces of a pressurized medium flowing through a gap that separates the rotors from the stationary housing. The rotors are coupled to a source of pressurized medium that creates a medium flow through the gap. The frictional forces between the flowing medium and the rotors create a torque that rotates the rotors. A compressor is formed of a rotor assembly that includes first and second counter-rotating rotors having subs...

The present invention relates to a rotary vice construction which can be specifically applied on the rotary table of a transfer machining apparatus, which vice comprises a first and second bodies, opposite to one another and forming a vice assembly adapted to hold a workpiece to be machined, which is supported by a rotary table. Inside each of the vice bodies there is rotatably supported a supporting shaft which supports the vice jaws for holding the workpiece, a removably locking ring element b...

The rotary machine can be used as a rotary internal combustion engine and as a pneumatic or hydraulic pump. The rotary machine comprises a housing in the form of two intersecting cylinder parts of different diameters having parallel axes. A rotor is received in the housing coaxially with the smaller-diameter cylinder and comprises at least two segmental rotor parts provided with annular rotor covers. At least two pairs of annular elements are provided engaging with the segmental rotor parts. Piv...

A rotary switch for installation in the dashboard of a vehicle has a switch housing, an actuation shaft that is arranged rotatably in the switch housing, a knob that is mounted on one end of the actuation shaft, and a ring-shaped faceplate that surrounds the knob and that is detachably fastened to the switch housing. The faceplate is connected to the switch housing by a locking mechanism. This locking mechanism can be released by a relative rotation between the faceplate and the switch housing. ...

A rotary seal housing having opposing ends, a first fluid conducting slot at one of the opposing ends, a pair of spaced apart fluid conducting slots at the other opposing end, and sets of apertures connecting the first fluid conducting slot with the pair of fluid conducting slots, the housing having helical push back grooves that are arcuate in cross-section.

Rotary press with a rotor, rotatingly drivable around a vertical axis of rotation, which has a die plate with die bores and upper and lower punches guided in guidings, radial cams for the upper and lower punches, at least one compression station with upper and lower pressing roller, at least one filling equipment and at least one stripping device for pressed articles which are ejected from the die bores, characterized in that the rotor has an annular plane situated radially outside of the gradua...

An overload clutch assembly for a power tool having two torque settings through which rotary drive is transmitted to a spindle. The overload clutch assembly is capable of being between switched between the two torque settings by at least one actuator. The clutch assembly comprises a carrier rotationally mounted on a output clutch spindle; a first clutch plate operational for transmitting torque below a first level; and a second clutch plate operational for transmitting torque below a second leve...

A rotary position sensing including a first and second magnet spaced from one another. A first and second triangular magnetic flux director are arranged in a generally diamond shaped configured with an air gap between the two magnetic flux directors. A magnetic field sensor system is positioned in the air gap between the magnetic flux directors. The magnets and the magnetic flux directors, with the magnetic field sensor system in the air gap, are rotatable relative to one another about an axis g...

A circular column-shaped flywheel rotor 4 that rotates inside a rotor housing 1 in which a cylindrical-shaped hollow section is formed; a piston head 34 that is located on the flywheel rotor 4 so that it can come in sliding contact with the inner peripheral wall of the rotor housing 1 or be released from sliding contact; an intake valve 10 and airtight-sealing valve 21 that are constructed so that they are capable of partitioning and dividing a combustion chamber or opening up the combustion cha...
