Abstract: A ball-nut steering system of a conventional vehicle includes a first and a second cylinder chamber for receiving a fluid, a first feed line for conducting fluid from a pump to the first cylinder chamber, and a device for damping and/or easing pulsations of the fluid. The device is arranged inside the first cylinder chamber and/or inside the first feed line. The first cylinder chamber has a smaller volume for receiving the fluid than the second cylinder chamber.

Abstract: A steering shaft for a steering system of a motor vehicle, comprises an inner shaft mounted axially displaceably in a hollow shaft, wherein a rolling bearing having multiple metallic rolling elements, which are disposed axially in at least two rows, is disposed between the hollow shaft and the inner shaft. Previously known steering shafts cannot reliably present vibrations from being transmitted from the inner shaft to the hollow shaft. Therefore, the diameters of the metallic rolling elements decreases proceeding from the center of the rolling bearing toward the end faces thereof, wherein multiple mutually adjacent metallic rolling elements have identical and/or different diameters.

Abstract: A power steering device for a vehicle which is disposed in the transmission path between a steering handle and a steerable vehicle wheel, comprises a servo cylinder having two pressure chambers, which are separated by a working piston and are each connected to a pressure supply unit. A valve plunger, which seals a bypass channel between the pressure chambers, is movably disposed on the working piston. Furthermore, an adjustment bushing comprising an adjustment section is disposed in the servo cylinder, the valve plunger being moved against this section upon approaching an axial limit position, thereby opening the bypass channel. The adjustment bushing is clamped into the servo cylinder, yet held displaceably, wherein, on the adjustment bushing, a sealing section is provided, which is to be moved into a sealing position with the working piston so as to interrupt the flow connection between the pressure chambers.

Abstract: A molding machine has a feed screw arrangement which plasticizes a material and which injects the plasticized material into a mold. The feed screw arrangement includes an input shaft which is mounted in a housing for rotation relative thereto and for axial displacement with and relative to the housing, the input shaft having a splined end portion which extends outwardly of the housing. The housing is mounted on a support for angular displacement about a pivot axis, and a drive is mounted on an auxiliary support for movement with respect to the support for the housing. The drive has an output shaft which has a central opening adapted to matingly receive the splined end portion of the input shaft when coaxial therewith. Relative axial displacement of the two shafts from an extended position in which the splined end portion is matingly received in the central recess to a retracted position in which the shafts are disengaged frees the feed screw arrangement for pivoting about the pivot axis.

Abstract: Two halves of a split mold of an injection molding machine are respectively mounted on a stationary plate and a movable plate guided on guide rods projecting from the stationary plate for movement toward and away from the latter. A guide plate, likewise guided on said guide rods, is connected to the movable plate for movement therewith, and a moving arrangement is connected to the guide plate for moving the same and the movable plate connected thereto toward and away from the stationary plate to thus move the mold halves between an open and a closed position. The guide plate includes a clamping arrangement for clamping the guide plate in fixed position on the guide rods and a hydraulically operated arrangement for holding the mold halves in closed position against the force of molding material injected under pressure into complementary cavities in the mold halves.

Abstract: An injection molding machine includes a stationary frame having a pair of spaced upright stationary plates which guide rods of a movable frame which includes, at opposite ends of the rods projecting beyond the stationary plates, a pair of movable plates. One of the stationary plates and the movable plate adjacent thereto respectively carry complementary parts of a split injection mold. A unit including a pressure plate fixed to the other stationary plate is arranged on the rods between the other of the stationary plates and the movable plate adjacent thereto. Cylinder and piston arrangement connects the unit and the movable plate adjacent thereto for moving the movable frame relative to the stationary frame and therewith the mold parts between open and closed positions.

Abstract: A machine for treating articles, such as containers, for example, includes an infeed worm conveyor to receive a continuous flow of containers. The speed of machine operation is regulated by a speed control mechanism so as to maintain a desired constant length accumulation of containers ahead of the infeed worm conveyor. The infeed worm conveyor is axially shiftable, under the influence of forces created by accumulated containers, to transmit such forces to the speed control mechanism as an indication of the size of container accumulation.
