  • Patent number: 7228941
    Abstract: The invention relates to a metering device for lubricant having a lubricant reservoir (1), a piston (3), which is arranged on a threaded spindle (2), within the lubricant reservoir and a drive head 4, which has a drive shaft (7) connected to the threaded spindle (2) and an electromechanical drive (5) for actuating the drive shaft. The drive shaft (7) contains a lubricant passage duct (8) which opens into the lubricant storage space of the lubricant reservoir. A ram (9) is inserted into the lubricant passage duct (8) of the drive shaft, said ram having an axial bore (10) with a nonreturn valve (11) on the inlet side, and also a ram head (13) which is arranged in a rotationally fixed manner and is loaded by a compression spring (12). The ram head (13) bears under the effect of the compression spring (12) against a control surface (14) of the drive shaft (7).

  • Patent number: 7178634
    Abstract: A device for supplying several lubrication points on machine parts with a lubricant, comprising an electromechanical lubrication dispenser and a distribution device coupled to a lubricant outlet of the dispenser. The distribution device has a housing, a cylindrical hollow distributor body or tube which is mounted to rotate about a vertical axis. There is also a fixed cylindrical sleeve that surrounds the distributor body, forming a seal. The distributor body has an opening at the top for allowing the lubricant in, and has at least two distributor bores disposed on the circumference but offset axially from one another. Each of these distributor bores has a corresponding opening bore in the distributor sleeve that is assigned to it. This distribution device also has an electric motor drive that has a running path control that has a switch that functions electromechanically or in a contact free manner.

  • Publication number: 20040182183
    Abstract: A measurement device is provided for early detection of damage to a machine part that is supplied with lubricant from a decentralized electromechanical lubricant dispenser. The device has a measurement sensor and a measurement instrument that has a circuit board having integrated circuits, interfaces for the measurement sensor and for a connection to an electronic control of the lubricant dispenser, as well as a battery, which is soldered onto the circuit board, in order to prevent voltage drops. The measurement sensor has a device for recording analog measurement signals, provided with power by the measurement instrument. Furthermore, the arrangement is made so that the integrated circuits release the power supply of the measurement sensor at predetermined intervals, only for a short period of time, and interrupt the power supply again after the current measurement values have been detected.

  • Patent number: 6601738
    Abstract: A lubricant dispenser comprising a housing, a lubricant supply container, a plunger, a telescopic hollow spindle, and an electromechanical servo-drive for changing the length of the telescopic hollow spindle. One end of the telescopic hollow spindle is fixed on the housing. With its other end, the telescopic hollow spindle cooperates with a plunger containing a passage opening for lubricant. The telescopic hollow spindle has a lubricant passage channel in which at least one check valve is arranged on the inlet side. The telescopic hollow spindle alternately carries out setting strokes of different lengths that increase or reduce the length of the spindle. The setting strokes are coordinated with each other so that with a setting stroke of the telescopic hollow spindle increasing the length of the spindle, a preset amount of lubricant displaced by the movement of the plunger enters the lubricant passage channel through the opening check valve.
