Abstract: A drive device includes a gear unit, which is able to be driven by a motor and includes a pressure-lubrication system. The pressure-lubrication system has a distributor block, having a continuous longitudinal bore and continuous transverse bores. The distributor block is arranged as a single piece, in particular from metal such as steel or aluminum.

Abstract: A fluid filtration assembly includes a filter housing having first and second ends and a connector for fluid communication with a fluid storage vessel. A filter element is disposable within the filter housing, and first and second pumps are coupled at the first and second ends of the filter housing. A controller may coordinate the operation of the first and second pumps to induce alternating tangential flow of fluid between the filter housing and the first and second pumps. At least one of the first and second pumps is a diaphragm pump or a plunger pump. The fluid storage vessel can be a bioreactor.

Abstract: A low-pressure pump supplies oil stored in a steering case to a steering device as lubricating oil via a steering lubricating circuit. A high-pressure pump supplies the oil stored in the steering case to a clutch via a high-pressure circuit. A transmission lubricating circuit branches off from the high-pressure circuit via a relief valve and supplies lubricating oil to a transmission device. A transmission-lubricating assist circuit is provided so as to branch off from the steering lubricating circuit and is connected to the transmission lubricating circuit. A transmission case stores the oil used to lubricate the transmission device. A scavenging pump returns the oil stored in the transmission case to the steering device.

Abstract: The invention relates to a device for lubrication of a work vehicle, which device includes: a tank (1) for storage of lubricant; a number of delivery points (8a-g) at which lubricant is supplied to the tools of the work vehicle or other parts that need to be lubricated; a distribution block (5) including a number of branching points (6a-g) that all are connected to a delivery point (8a-g); a pump (2) for delivering lubricant from the tank (1) to the distribution block (5) and further on to the delivery points (8a-g); a control system (3), for regulating the supply of lubricant.

Abstract: A lubrication system is provided that includes a pump operatively connected to one or more supply lines for delivery of a lubricant, the system including a first pressure sensor associated with the supply line at a first position, and a second pressure sensor associated with the supply line at a second position downstream of the first position and pump, a controller configured to receive pressure signals and control operation of the pump based upon the pressure differential between the pressures at the first position and second position. The pressure differential may be employed to determine when a pressure at a third position downstream of the second position has been achieved. At least one of the pressure sensors may be positioned adjacent to the pump, the controller further being operable to deactivate the pump in the event that a maximum pump pressure has been met.

Abstract: An internal combustion engine in which it can be made difficult for bubbles to mix into oil in a flowing-down process of the oil. In a generator chamber, a shielding rib is provided which is disposed between a generator and an oil introduction port in side view and which extends skewly upwardly from the oil introduction port in a manner so as to cover one end side of the oil introduction port. A guide rib extends from a side wall of the generator chamber in the manner of covering the other end side of the oil introduction port.

Abstract: A continuously variable transmission in which a sliding member is prevented from inclining is provided. The continuously variable transmission has a first oil passage provided in a movable sheave, and a second oil passage provided in a primary shaft supporting the movable sheave and connected in series to the first oil passage. A working oil is discharged from a hydraulic chamber via the first and second oil passages. The working oil is more difficult to discharge from the second oil passage than the first oil passage.

Abstract: A device that relieves lubricant pressure in a divider block lubrication system into a fluid reservoir, a container, or directly back into the compressor frame to which the tubing is connected. This eliminates housekeeping, environmental, safety, and compressor component failure concerns associated with current atmospheric rupture assemblies that relieve directly to the atmosphere. The environmental compressor protection assembly contains a spring set to a pre-determined pressure. Lubricant pressure in excess of this pre-determined set pressure results in spring compression and opening of a relief path. The assembly preferably remains in a full open position and must be must be manually reset to the closed position to prevent fluid flow in the system. The relief path can lead to a fluid reservoir, a container, or directly back into the compressor frame. Flow of lubricant through the relief path results in loss of flow to the lubrication system.

Abstract: A rock breaking machine and to a method of lubricating a tool of a rock breaking machine. The lubricating system comprises at least one lubricant channel (23) into which lubricant is fed by a lubricating device (24). Lubricant is supplied to the bearing members (19) of the tool (6, 13) of the rock breaking machine. The lubricating device comprises a lubricant container (25) and a transfer device (26). The transfer device (26) controls the feed of lubricant into the lubricant channel. The lubricant container (25) is integrated into the body (17, 18) of the rock breaking machine.

Abstract: A controller for controlling a medium flow fed from a supply to at least one hydrostatic or aerostatic pocket of a bearing, a threaded spindle nut or a guide, having a housing and having pressure chambers which are separated by a control element, movable against the force of a spring element, and of which a first pressure chamber, subjected to a first pressure level, is directly connected to the medium supply, a second pressure chamber, subjected to a lower, second pressure level, is connected to the medium supply via a first flow resistance, and a third pressure chamber, which is subjected to a third pressure level which corresponds to that in the pocket, is connected to the pocket, a control element forming a variable second flow resistance is arranged between the second and third pressure chambers influencing the medium flow to the pocket and whose magnitude is raised by the action of the force of the first pressure chamber but is lowered by the action of the spring force and by the actions of the forces o

Abstract: The invention pertains to a regulator for regulating a medium flow to at least one hydrostatic or aerostatic pocket of a bearing, a nut for threaded spindles or a guidance from a medium supply, with pressure chambers that are separated by a variable flow resistance control element that can be moved against the force of a spring element. A first pressure chamber is directly connected to the medium supply, a second pressure chamber that is charged with a lower pressure level is connected to the medium supply via a first flow resistance, and a third pressure chamber is charged with a third pressure level that corresponds to the pressure in the hydrostatic or aerostatic pocket.
