The invention relates to a propulsion power transmission device having a first interface (1) and a second interface (2). According to the invention, a hydrodynamic clutch is mounted in the driving connection between the first interface and the second interface and a first gear train (4) and a second gear train (5) are mounted parallel to each other in the driving connection, in series with the hydrodynamic clutch, the second gear train (5) causing a reversal in the direction of rotation in relation to the first gear train (4) at one of the two interfaces (1, 2). The propulsion power transmission device of the invention is characterized by the following features: the hydrodynamic clutch has two separate working chambers (3.1, 3.2), which can be independently filled with and drained of a working medium in order to transfer torque from one bladed primary wheel (3.3, 3.4) to at least one bladed secondary wheel (3.5) of the hydrodynamic clutch (3), with the blades of the primary wheels and of the at least one secondary wheel being arranged opposite each other; the first gear train and the second gear train (5) are respectively continuously connected to the first primary wheel (3.1)1 and the second primary wheel (3.2)2 in a driving manner; and both gear trains (4, 5) are continuously connected to one of the two interfaces (1, 2) in a driving manner.

A combination gear having a simple structure is provided at low cost without increasing a number of components. In at least two gears adjacent in an axial line direction and having a same rotation direction, three engaging portions arranged in a regular triangle are formed at an end of one of the adjacent gears and a regular triangle engaging hole is formed at an end of another gear. The engaging portions and the engaging hole fit together with play remaining, and when one of the gears rotates, the three engaging portions and three surfaces of the engaging hole engage such that the other gear rotates coaxially, and when rotation stops, the engaging portions and the engaging hole move in a direction orthogonal to the axial line by a play amount and become eccentric.

An actuator assembly for a welding gun is provided that has at least three positions in the example. The actuator assembly includes separate working and retract actuators. The working actuator includes a working rod movable between first and second positions. The retract actuator includes a retract rod independently movable relative to the working rod between third and fourth positions. The retract actuator is external to and non-concentrically arranged relative to the working actuator in the example shown. Actuation of the working and retract actuators is coordinated to provide at least three positions while enabling the actuators to be changed or modified independently from one another. A latching device is configured to selectively interlock the working and retract actuators to one another automatically in response to movement the working rod from the first position to the second position.

A cam follow arrangement has a rectangular-shaped through hole formed in an end portion of a ram member, the through hole having first and second opposed ends and a pair of parallel sides. A slider which is disposed in the rectangular-shaped through hole is configured to be slidable back and forth along the parallel sides toward and away the first and second ends. A spring is disposed between the slider and the first end of the rectangular-shaped through hole to bias the slider toward the second end of the rectangular-shaped through hole.

A device for setting a relative rotational position of a gearwheel and a ring gear disposed coaxially mounted and turnable on an annular extension of the gearwheel includes a plurality of radially extending pressure levers actuatable in common by an axially adjustable, centrically disposed adjusting element for releasing a spring-biased positive connection of mutually engaging faces of the gearwheel and the ring gear by reducing the spring bias acting upon the faces, the pressure levers being loosely disposed between the annular extension of the gearwheel and a clamping disc adjacent thereto, the pressure levers being received in radial grooves formed in the clamping disc and being pivotally braced at a first contact region located between the ends thereof against one of the annular extension and the clamping disc, the adjusting element being displaceable over a distance, during a first portion of which the spring bias increases from a relatively low value to a value necessary for maintaining the relative rotational position of the gearwheel and the ring gear and, during a second portion of the distance displaceable by the adjusting element, the spring bias necessary for maintaining the relative rotational position of the gearwheel and the ring gear is at least maintained, and an electric switch connected in a supply-current circuit of a machine drive is actuatable by the element.

A dynamically variable oscillating adjustment assembly including a frame and a first link means pivotally connected at one end to the frame and an adjustment mechanism positioned intermediate the one end of the first link means and the frame to adjustably position the first link means with respect to the frame. A second link means pivotally connected at one end to the other end of the first link means and pivotally connected at the other end to a first arm of a bell crank pivotally mounted upon the frame. A second arm of the bell crank is operable to oscillate in response to oscillation of the other end of the first link means. An adjustment mechanism may be interposed between the frame and the intermediate pivot of the bell crank such that the position and stroke of the other arm of the bell crank may be selectively adjusted.

An arrangement for use in a conveying and filling device where a conveyor is provided which travels along a linear path in a selected direction to carry articles, for example, recepticles to be filled. A dispensing device is carried by a mounting arm located in spaced relation from the conveyor and is carried by crank means to travel in an orbital path where the orbit carries the mounting arm in the direction of movement of the conveyor for the first portion of the orbit at the termination of which the orbital path returns the mounting arm to a second position relative to the conveyor for a second cycle over the conveyor, including a height adjusting arrangement to adjust the clearance between the mounting arm and the conveyor.

A variable angle wobble plate drive for varying piston displacement has constant velocity coupling from the wobble plate to the frame which permits all axis-dynamic balancing. The coupling uses an idler element rotating on a tilted axis portion of the shaft, and conical gear sets connecting the idler member to the machine frame and the idler member to the wobble plate. The sum of the acute angles from the tilted axis to the shaft, and to the driving axis, is made greater than the maximum driving angle thereby permitting low reaction torque on a driving angle control mechanism without reversal of control torque.

According to the depicted embodiment, the novel ancillary valve rocker means comprises an ancillary valve rocker which is mountable atop the standard valve rocker, and which has a longer pivot arm, and first and second rods which communicate movement from the standard valve rocker to one end of the ancillary valve rocker, and translate the movement into a greater translation of the valve rod. The first and second rods, secondary push rods, are more widely spaced apart, whereat they engage the ancillary valve rocker than where they engage the standard valve rocker and valve rod end, and this together with the longer "reach" of the ancillary valve rocker causes the valve rod to move through an exaggerated translation. The inventive rocker means are adjustable, whereby the amount of valve rod movement may be selectively determined.
