20080217106 | Metering device for a lubricant dispenser - A metering device for a lubricant dispenser has an inflow opening and at least two outflow openings for dividing up the amounts of lubricant being conveyed, and has a slide inserted into a housing of the metering device so as to move lengthwise, which slide has an axial bore on the inflow side. The outflow openings are connected to the axial bore of the slide on the inflow side by way of a displacement chamber, in each instance. The displacement chambers are hydraulically separated from one another by kickback valves. A forward stroke of the slide brings about a reduction in volume of the displacement chambers and flow of the lubricant out of the outflow openings. A backward stroke of the slide brings about an increase in volume of the displacement chambers and follow-up flow of the lubricant through the kickback valves. | 09-11-2008 |
20080230318 | Lubricant dispenser - A lubricant dispenser has a lubricant container that has an outlet opening for lubricant, and has a piston disposed in the lubricant container. The piston can be moved towards the outlet opening for the purpose of dispensing lubricant. There is at least one prong that presses against the inside wall of the lubricant container, is made of a harder material than the lubricant container and is disposed on the piston circumference. | 09-25-2008 |
20080271950 | LUBRICANT-DISPENSING SYSTEM AND METHOD OF OPERATING SAME - A lubricant dispenser has a housing whose interior is subdivided by a shiftable piston into a generally closed gas compartment and a lubricant compartment having an outlet port and filled with a body of lubricant. A gas generator associated with the gas compartment is electrically energizable to produce gas and thereby pressurize the gas compartment, shift the piston, and express lubricant from the outlet. A controller including a power supply and a circuit is connected between the power supply and the gas generator for feeding current from the power supply to the gas generator. During a first predetermined part of an operational cycle of the dispenser, the gas generator is energized at a first level. During a second predetermined part of an operational cycle after the first time, the gas generator is energized at a second level lower than the first level. | 11-06-2008 |
20080271951 | Method for dispensing lubricants, and gas production element for carrying out the method - A method for dispensing lubricants uses a lubricant dispenser that has a lubricant reservoir connected to a housing outlet in a housing, and a gas production region that borders on the lubricant reservoir and accommodates an electrolyte fluid. To start dispensing the lubricant, a galvanic gas production element is introduced into the electrolyte fluid, whereby the lubricant is pressed out of the lubricant reservoir, through the housing outlet, under the pressure of a gas that is produced via electrochemical decomposition of the gas production element. An additional component is introduced into the electrolyte fluid at the same time with the galvanic gas production element, which component is decomposed in the electrolyte fluid during a shorter period of time, with reference to the entire period of operation, with the production of gas, and thereby brings about an increase in the gas production rate, part of the time. A gas production element for carrying out the method is also disclosed. | 11-06-2008 |
20090038888 | Lubricant Dispenser - A lubricant dispenser has a housing that has a bottom with a housing opening, a lid, and a housing mantle between them, a lubricant reservoir, and a gas generator disposed in the housing for pressing the lubricant out. The housing mantle is transparent or translucent, at least in some sections, and has at least one barrier layer. The barrier layer has a polymer base substance and an admixture of typically inorganic layer substances to improve the barrier properties. | 02-12-2009 |
20110296902 | METHOD FOR METERED DISPENSING OF LUBRICANT - The invention relates to a method for metered dispensing of lubricants using a lubricant dispenser comprising a reservoir chamber filled with lubricant, a gas generating unit for electrochemically generating gas, a piston acted on by the generated gas for outputting the lubricant from the reservoir chamber, and an electronic control unit for controlling the electrochemical gas generation. According to the invention, the temperature of the lubricant or the environment is measured at time intervals, and an average temperature value is derived from a plurality of measured temperature values. Using stored correction values describing the temperature-dependence of the electrochemical gas generating rate, a control parameter determining the electrochemical gas generation is set for the average temperature value, having the requirement that the gas generating rate at the average temperature value corresponds to the target value that correlates to prescribed dispensing time. | 12-08-2011 |
20130206511 | CONTAINER FOR COLLECTING WASTE LUBRICANT - A container for collecting a liquid lubricant has a housing having one end formed with an inlet opening connectable to a source of the liquid lubricant and an opposite end formed with a vent hole, with a piston inside the housing subdividing the housing into a front lubricant compartment into which the inlet opening opens and a rear compartment into which the vent hole opens. The piston is shiftable between a front position close to the intake opening and a rear position close to the vent hole such that as the liquid lubricant fills the lubricant compartment the piston moves into the rear position. Formations on the piston and on the housing seal between the piston and the housing around the vent hole only when the piston is in the rear position. | 08-15-2013 |
