摘要： A track frame or undercarriage is made to support a rubber track on suitable guide rollers. A tensioning roller is provided as one of the guide rollers on the interior of the track and is mounted on a pivoting bracket. The pivoting bracket moves the tensioning roller to a working position for creating tension in the track. An actuator provides a known force on the pivoting bracket to move the tensioning roller to its working position, using a controlled pressure applied to the actuator. Drive sprockets for the track are mounted onto a drive case that is mounted to the frame through pivoting linkages such that the drive case and the drive sprocket can be held in a working position and retracted away from the track. The position of the tensioning roller is maintained within set limits of retractions during use, by providing a stop to limit the amount that the tensioning roller can retract.

摘要： A fuel pump for an internal combustion engine, comprising a housing (14) in which a piston (16) is guided. A working chamber is confined in areas by the piston (16). An eccentric shaft or camshaft acts on the piston (16) on its end furthest from the working chamber. A prestressing element (30) loads the piston (16) against the eccentric shaft or camshaft.

摘要： In a fuel injection pump, a tappet is provided on an end thereof on a side of a cam ring with a hollow. Force acting on the tappet from a plunger due to fuel pressure is dispersed to a sliding contact surface outside the hollow so that contact face pressure between the tappet and the cam ring is smaller. As the fuel pressure becomes higher, larger resilient deformation of the tappet causes a diameter of the hollow smaller so that the tappet comes in flat slidable contact with the cam ring, resulting in preventing the contact portion between the tappet and the cam ring from being seized with frictional heat.

摘要： The invention relates to a hydraulic pump unit with an electric drive motor and a radial piston pump that is provided as a return feed pump for a motor vehicle for a slip-regulated, hydraulic brake system. To drive the pump pistons, the invention provides a rod-shaped eccentric element that is supported eccentrically with ball heads in a shaft end of a drive shaft of the drive motor and disposed on an opposite side of the pump pistons in a pump housing is supported so that the eccentric element can swivel around a solid angle. When the drive shaft is rotated, the eccentric element executes a movement on a surface of a cone so that the pump pistons resting against the eccentric element are driven in a reciprocating stroke motion. The invention has the advantage of a mechanically defined bearing support of the drive shaft and eccentric element so that the bearing of the eccentric element, which bearing is fixed to the housing, does not have to be exactly flush with the drive shaft.

摘要： In the inventive plunger pump, a plunger is pressed on a shaft by a spring via a thrust bearing having rolling elements clamped by a pair of bearing washers. By such a configuration, the motion of the shaft is immediately transmitted to the plunger, irrespective of whether the radius of the profile of a cam for driving the shaft back and forth is in the increment phase or decrement phase, so that the suction and discharge of liquid is performed without delay, since no play (or gap) exists in the transmission mechanism between the cam and the plunger. Thus, the fluctuation in the pressure is minimized during the operation of the pump and, when a low pressure gradient elusion is carried out, the solvents are supplied at the desired flow rates accurately.

摘要： An abrasion preventing device for a hermetic reciprocating compressor. The device releases the impact generated between the slider and the shell of the compressor, thus to prevent possible abrasion of the contact part between the slider and the shell as well as abrasion of the piston. The device comprises a cylinder and a piston received and reciprocating in the cylinder, an end of the piston having a coupling projection. A shell, which is coupled to the piston, has a coupling projection. A bolt and nuts are used for coupling the piston to the shell by coupling the projections of both the piston and the shell to each other. A spring is provided on a coupling portion between the piston and the shell for absorbing the impact caused by striking of a slider on the shell during an operation of the compressor.
