  • Patent number: 7498932
    Abstract: An internal combustion engine in a working device comprises an oil reservoir near a crankcase to hold oil. An oil measurement device is used to recognize the existence of oil in the oil reservoir and to produce a corresponding signal that is evaluated in an evaluation device to produce an oil level reading. The oil level reading is preferred to be produced only during the starting of the internal combustion engine or within a specific time period after starting the internal combustion engine. When the internal combustion engine has reached its operating RPM, no further oil level monitoring is performed.

  • Patent number: 6779633
    Abstract: An improved system for changing the fluid of vehicular automatic transmissions and the like, which has the capability to provide a complete fluid exchange faster and with less usage of fresh fluid in a manner that is easier to operate. This is accomplished by the system's unique capability to extract used fluid and replace it with fresh fluid at a faster, balanced rate than before possible in prior art. This is accomplished by decreasing or removing restriction from the exhausting of the used fluid and introducing fresh fluid at more than one locus. The unique, novel capability of the invention to use a dual use pan access tube to combine a static change with a dynamic change, and to introduce fresh fluid into the transmission from two different loci instead of one as in all prior art, allows the fluid exchange to be completed in a shorter time with less use of fluid.

  • Patent number: 6349692
    Abstract: An apparatus for reducing wear in an internal combustion engine includes a pump, a control element, an external controller. The apparatus of the preferred embodiment is intended to be located inside an internal combustion engine, thereby eliminating most hardware. The control element is connected to a normally provided battery and automatically switches control power from the battery to the electric pump according to a programmed control operating cycle program, and is operatively independent of ignition switch activation or operator action. The inlet of the pump is immersed in oil inside the normally provided engine oil sump. The lubricating fluid is pumped through the high arrestance filter, yielding a substantially contaminant free lubricating fluid which flows into the normally provided engine lubricating gallery. The external controller, such as a wireless remote control, is provided to activate the pump remotely upon demand.

  • Patent number: 6330934
    Abstract: An improved system for changing the fluid of vehicular automatic transmissions and the like, which has the capability to provide a complete fluid exchange faster and with less usage of fresh fluid in a manner that is easier to operate. This is accomplished by the system's unique capability to extract used fluid and replace it with fresh fluid at a faster, balanced rate than before possible in prior art. This is accomplished by decreasing or removing restriction from the exhausting of the used fluid and introducing fresh fluid at more than one locus. The unique, novel capability of the invention to use a dual use pan access tube to combine a static change with a dynamic change, and to introduce fresh fluid into the transmission from two different loci instead of one as in all prior art, allows the fluid exchange to be completed in a shorter time with less use of fluid.

  • Patent number: 6296078
    Abstract: An axle bearing lubricating device includes a grease storage tank for providing lubricating grease to at least one grease propeller, the grease storage tank having a grease outlet, at least one grease propeller for propelling grease from the grease storage tank to a respective axle bearing, the at least one grease propeller each having a piston reciprocated to expel lubricating grease to a respective axle bearing, a manifold connected between the grease outlet of the grease storage tank and air holes on each grease propeller, and a high pressure system controlled to output high pressure air to the at least one grease propeller to reciprocate the piston in each grease propeller for enabling lubricating grease to be applied to each axle bearing.

  • Patent number: 6244385
    Abstract: A lubrication pressure controller comprises a lubrication pressure regulating valve 41, which is provided in a lubrication oil passage 36 directing hydraulic oil to lubricated parts, and a cooler pressure regulating valve 42, which is provided in a discharge oil passage 51b of the lubrication pressure regulating valve 41. The lubrication pressure regulating valve 41 adjusts the pressure in the lubrication oil passage 36, and the cooler pressure regulating valve 42 adjusts the pressure supplied to an oil cooler 55. The hydraulic oil discharged from the cooler pressure regulating valve 42 is returned through a recirculation line 52 to a suction oil passage 31 of a pump. In this construction, an adequate supply of lubrication oil is maintained even if one of the valves experiences locking of a valve spool on an open side.
