Displacement By Liquid Patents (Class 184/54)
  • Patent number: 9856880
    Abstract: A motor includes a metal base plate and a resin holder extending upward from the base plate. The base plate includes a flat plate portion, a through hole passing through the flat plate portion, and a plurality of claw portions extending upward from an edge of the flat plate portion which includes the through hole. A portion of the holder is in the through hole. The holder covers a portion of each claw portion. The holder is thus engaged with each claw portion to prevent the holder from turning around a rotation axis and from coming off in an upward direction. The holder includes a gate mark near a lower surface of the flat plate portion and at a circumferential position between adjacent ones of the claw portions to make it easier for the resin to fill a cavity inside molds during a molding process.

  • Patent number: 8607934
    Abstract: The present invention is an air/hydraulic injection lubrication unit. The present invention is embodied in a handheld lubrication system conveniently transported in a carrying case. A frame provides a base on which the system components are mounted. The system components include a lubricant barrel assembly in conjunction with a cradle assembly and an air/hydraulic pressure pump removably-mounted upon the frame. A hose assembly at one end is releaseably fastened to the discharge end of the lubricant barrel assembly. When the air/hydraulic pressure pump is activated, the lubricant or other material in the lubricant barrel is forced out of the hose assembly through a lubricant discharge unit located at the opposing end of the hose assembly.

  • Patent number: 7861827
    Abstract: A bearing oil supply assembly includes (a) a plate member with opposed first and second sides, the plate member having a first bore formed in the first side which is adapted to receive a first bearing; (b) an annular manifold attached to the plate member such that the plate member and the manifold cooperatively define an annular oil gallery; and (c) a plurality of passages formed in the manifold, the passages cooperating with the plate member to define a plurality of generally axially-directed pathways in fluid communication with the first bore and the oil gallery. The passages are substantially evenly spaced around the circumference of the manifold. The oil supply assembly may be used to supply oil to two bearings carrying separate shafts running at different speeds.

  • Patent number: 7210561
    Abstract: A lubricating device of a reciprocating compressor includes a pumping unit for pumping lubrication oil contained in a lower portion of a case and a front frame having a supply hole which supplies the lubrication oil pumped from the pumping unit to a sliding part within the case and a discharge hole which discharges the lubrication oil upon completion of a lubrication operation. A lubrication oil storage is arranged at a front of the discharge hole for storing the lubrication oil discharged to the discharge hole for a predetermined time and then discharging the lubrication oil. A lubrication oil guide is provided for guiding the lubrication oil discharged from the discharge hole to a lower portion of the case in order to prevent the lubrication oil discharged through the discharge hole from flowing to an air hole formed at a front frame.

  • Patent number: 5566781
    Abstract: Apparatus and methods for flushing and cleaning the oil strainer and crankcase of an internal combustion engine of a type having a removable full-flow oil filter. The oil filter is temporarily replaced with a cartridge which has at least one passage therethrough which will communicate with the discharge side of the engine oil pump but does not communicate with the normal outflow port of the filter apparatus. A second passage therethrough may communicate with the outflow port of the filter system but does not communicate with the discharge of the oil pump. In a preferred method, the inlet of the first passage may be connected to a source of pressurized fluid to force the fluid, in a direction opposite to normal flow, through the passage, the oil pump and the oil strainer to agitate and flush contaminants in the oil strainer and crankcase. The pressurized fluid and contaminants are drained from the crankcase after which the cartridge is removed, a new oil filter installed and clean oil added to the engine.

  • Patent number: 4593775
    Abstract: A pressure compensating lubricant reservoir system is disclosed for a rotary cone rock bit. The system comprises a two-piece canister and flexible boot, one side of the boot being vented to the dome area of the bit. An O-ring is utilized adjacent the reservoir cover cap to seal the lubricant within the reservoir cavity. In order to prevent damage to the O-ring, the cover cap part of the canister forms a circumferential groove therearound to accept the O-ring. An intermediate disc is trapped between the cover cap and the resilient boot and serves to close out the O-ring groove in the cover cap.With a prior art one-piece canister, the O-ring is put into position in a groove formed by the canister, followed by insertion of the canister into a lubricant cavity formed by the bit body. Damage to the O-ring often occurs when the outer peripheral edge of the O-ring passes by a cover cap snap ring retention slot at the reservoir cavity entrance.
