  • Patent number: 8196489
    Abstract: Described is a lubricating device with at least one lubricating pinion for applying a lubricant, in particular grease, which is for example fed through a lubricant line by a lubricant pump from a reservoir, to at least one gearwheel or the like, wherein the lubricating pinion has an outer toothing into which at least one lubricant outlet opens out. The teeth of the outer toothing of the lubricating pinion have a shortened tooth flank profile in relation to an involute toothing, wherein the addendum and/or the width of the tooth flanks in the peripheral direction are reduced in a tooth flank section which is situated radially outside the reference circle.

  • Publication number: 20120067897
    Abstract: The invention pertains to a lubricant collection container with a dimensionally stable enclosure and a collection bag accommodated therein, wherein the collection bag is fixed in the dimensionally stable enclosure by means of a holding device and is stabilized during movement of the lubricant collection container such that the collection bag cannot move freely during movement of the lubricant collection container. The holding device comprises a folding insert with a base plate and a membrane that at least partially covers the base plate, wherein the collection bag is essentially arranged between the base plate and the membrane and the membrane preferably covers the collection bag completely in the folded state of the folding insert in order to fix and stabilize the collection bag in a simple fashion.

  • Publication number: 20110005866
    Abstract: The invention relates to a lubricant dispenser having a storage container, an outlet channel, and a pump element disposed between the storage container and outlet channel for conveying lubricant. A piston is sealed in a cylinder and is movable between two positions, of which, in a suction position, the cylinder is in a flow connection with the storage container. The cross-section area of the piston is smaller than the cross-section area of the storage container. The piston and the cylinder are adapted to one another such that, upon a movement of the piston into the suction position thereof, a negative pressure may be generated in the cylinder as compared to the pressure in the storage container for taking in or letting in lubricant from the storage container into the cylinder, and such that, upon a movement of the piston in the opposite direction out of the suction position in the cylinder, a positive pressure may be generated for conveying the lubricant out of the cylinder into the outlet channel.

  • Publication number: 20100166581
    Abstract: The invention relates to a lubricant or hydraulic pump for delivering oil or the like having a housing which is formed from two housing shells which are of at least substantially similar or identical construction. An inlet is provided on or in the housing. Furthermore, a rotatably mounted drive element, which is configured, in particular, as a swash plate, and at least one pump element which interacts with the drive element to deliver oil or the like are arranged in the housing.

  • Patent number: 7726448
    Abstract: A distributor element, in particular a feed distributor, is provided for the metering of lubricants for lubricating installations. The element includes a valve piston featuring a bore. The valve piston moves under the pressure of a lubricant operating at a lubricant inlet against the force of a first return spring from a starting position in which the bore releases a connection between a dispensing chamber and a metering chamber via a connecting passage, to a metering position in which the valve piston releases a passage from the lubricant inlet to the connecting passage and therefore to the metering chamber. Furthermore, the distributor element features a dispensing piston which under the effect of a lubricant entering the metering chamber moves against the force of a second return spring from a starting position and thereby pushes the lubricant volume present in the dispensing chamber between the valve piston and the dispensing piston into a lubricant outlet.

  • Patent number: 6631787
    Abstract: A lubrication system for a vibratory apparatus such as a hydraulic striking device. The system includes a lubricant pump for pumping lubricant to one or more points of lubrication on the device and a drive for the pump powered in response to vibration of the device. The system includes a base for attachment to the device for vibration therewith, and a lubricant pump for pumping lubricant from a supply. The pump includes a cylinder and a plunger reciprocable in the cylinder through a stroke between a retracted position for intake of lubricant into the cylinder and a forward position for delivery of the intake from the cylinder. A weight is mounted on the base for oscillation in response to the vibration of the device, oscillation of the weight effecting reciprocation of the plunger through a stroke.
