The invention is characterized in that the cylinder liner ends at most 10 mm below the bottom dead center, and edge regions of the cylinder bore below the cylinder liner consist of the aluminum diecasting alloy.

Abstract: A drive arrangement for a conveying device for the conveying of a flowing medium is described, particularly for the conveying of air or fluid. The drive arrangement contains a drive engine whose rotational speed can be varied, an auxiliary motor that can be continuously controlled and a summing gearbox. The summing gearbox is connected on its output side with the conveying device and on its input side with the drive engine and the auxiliary motor. Furthermore, the drive arrangement contains a control unit that controls the auxiliary motor. In order to make possible an improved control or regulation of the conveying performance compared to linear, rigidly driven conveying devices, it is proposed that at least one magnitude of the condition of the flowing medium be detected by at least one sensor and to control or regulate the auxiliary motor of the drive arrangement by the control unit as a function of at least one magnitude of the condition of the medium.

Abstract: A PTO clutch of an agricultural vehicle connects an input driveline to an output driveline for coupling to an attached implement. A method and system for controlling the PTO clutch includes sensors for sensing rotational speeds on both sides of the clutch. Clutch slip is determined from the sensed speeds. A controller receives an actual slip signal and a desired slip signal and controls pressure in the clutch to maintain a constant desired clutch slip in order to avoid overload conditions. The torque transmitted by the clutch is determined as a function of the slip in the clutch and the clutch pressure, and a signal representing this torque is displayed to an operator.

Abstract: A venting or pressure release system releases pressure from a transmission housing through which extends a transmission shaft. A lower part of the transmission housing forms a collector in which fluid collect. A conduit communicates the collector with a storage container which is substantially sealed against the transmission housing. An overpressure in the transmission housing forces fluid from the collector through the conduit into the storage container. A pressure-release conduit communicates the transmission housing above the collector to the storage container. A shutoff device closes the pressure-release conduit when the transmission shaft is rotating and opens the pressure-release conduit when the transmission shaft is not rotating. This makes possible a rapid compensation of fluid after the transmission has been turned off so that the fluid level can be reliably determined. The shutoff device may be a pilot-controlled valve or a fluid barrier.

Abstract: A control device for the parking brake of a motor vehicle has a hydraulic cylinder with a piston chamber that can be pressurized by means of a valve arrangement, and has a hydraulic piston connected mechanically to engagement elements of the parking brake. The parking brake is forced into an engaged or disengaged position depending on the hydraulic pressure in the piston chamber. The piston chamber connects to a pressure sensor providing pressure signals that represent the state of the parking brake and that are evaluated by an electrical control unit. The control unit defines a first predetermined pressure threshold corresponding to the engaged state of the parking brake, and a second predetermined pressure threshold corresponding to the disengaged state of the parking brake.

Abstract: A control device for the parking lock of a motor vehicle has at least one actuating drive (46) that can be operated by triggering means and with which a locking device (11) can be moved between engaged and disengaged positions. For reliable operation, at least two independent triggering means are provided and a change in position takes place only if both triggering means (56, 58) are actuated. Preferably a hydraulic piston (46) brings the parking lock into its disengaged position when subjected to pressure. The triggering means are constructed as solenoids (56, 58) under the control of two electrical controllers (140,142) that undertake an evaluation of relevant control and measurement parameters.

Abstract: An emergency release device for the parking lock of a motor vehicle is described which contains an locking device (46,44,38,24,12,10) that is pressed into its engaged position by a spring element (42,50) and which can move into its disengaged position by at least one actuator (46) that is actuated by a control element (56,58) against the spring force. The locking device (46,44,38,24,12,10) can be linked with a clutch pedal located on the operator's station by releasable mechanical connecting elements (108,110,112), in such a way that it is possible to emergency-release the parking lock in case of vehicle malfunction.

Abstract: A device for dosing medicinal fluids, in particular a feeding solution for enteral alimentation, has a pump unit (2) with a displacement element (15) and a drive unit (3) for the displacement element. The pump unit (2) can be separated from the drive unit (3) and is realized in the form of a non-reusable, disposable item. After the device has been used, the pump unit is simply replaced with a new pump unit, so that it is unnecessary to clean the parts of the dosing device that carry the fluid.

Abstract: The invention relates to a device for securing a receptacle housing, positioned at the end of a cable, in an opening of a wall. The receptacle housing and the opening have a generally rectangular cross-sectional area and can be connected with each other in at least two positions, offset by 90.degree. from each other. The receptacle housing has detent springs which engage with the wall, from behind. A securing strap is fixed on the cable which is connected to the receptacle housing. The other end of the securing strap is connected to a cover. The cover can be mounted on the contact side of the receptacle housing. The cover can be guided through a groove-shaped recess while the securing strap is pushed through a side wall of the opening. The alignment between receptacle and opening, without impairment of the passage of the securing strap, is achieved in that the opening of the wall only has recesses for the securing strap of the cover in two side walls, located at right angles to each other.

Abstract: A vehicle, such as a tractor, has a main change-speed gear with an associated clutch and a load shift gear coupled to a selector rod. The load shift gear can be shifted under load between a normal position and an under-speed position which produces increased tractive effort by reducing the speed by about 20%. This load shift gear can be operated by the same lever as operates the main change speed gear. In order to prevent simultaneous operation of the main gear and the load change gear, with corresponding interference with the synchronization of the main gear, an interlock device is provided. The interlock device includes a bellows which is connected into the hydraulic circuit for the clutch and, when the clutch pedal is depressed, the bellows holds a plunger in interlocking engagement with one of two grooves in the selector rod which is mechanically coupled to the load change gear. In other embodiments, a mechanical linkage between the clutch pedal and the interlock device is provided.

Abstract: A power take-off lever arrangement for a tractor is disclosed which prevents the inadvertent shifting of the PTO lever to an engaged position. The lever arrangement includes a support plate secured to the tractor which has a pin extending outward from it which engages in a slot formed in the manually shiftable lever. Secured to the pin is an arcuate sector which has a recess formed in its arcuate surface. A roller, which is attached to the underside of the lever, will engage the recess when the lever is in a disengaged position and will ride on the arcuate surface when the lever is in an engaged position. The lever arrangement further includes a spring which is attached between the lever and the support plate to urge the roller into the recess when the lever is in the disengaged position.
