摘要： A gear pump 1' for operating with reduced likelihood of cavitation occurrences in the fluid being pumped thereby comprises a pair of gears (2,3) each supported on a corresponding one of a pair of gear shafts (4,5). Teeth provided in each gear (2,3) mesh with at least one tooth of the other when such teeth have been rotated into a meshing region (7) in the gear plane. One of the gear shafts (4,5) is rotatably connectable to a motor. Bearing structures (11) rotatably support corresponding ones of each of the pair of gear shafts (4,5) with the bearing structures (11) having bearing surfaces (11') adjacent those gear sides. A pressurized fluid passageway (20) is provided in at least one of the bearing structures (11) across from the meshing region (7) and extending between surface openings (22,21) at the bearing surface (11') of that bearing structure (11) that are positioned on opposite sides of an alignment axis in that bearing surface (11'), the surface openings (22,21) being separated from one another by at least the width of a tooth provided in the pair of gears (2,3).

摘要： A low noise gear set 300 for use generally and preferably with a power plant 11 having an engine 12 driving a pump 16 connected to a low pressure fluid source 18, generating high pressure fluid at an output 107, 252, 254. The idle gear 312 meshes with the drive gear 310 along two points 314, 316 of the profile 318, 320 of the corresponding gears 310, 312. The first point 314 being the root 326 of one gear tooth meshing with the tip 328 of the opposite gear tooth creating an initial first contact point 314 and a subsequent second point 316 along the profile 318, 320 when the teeth are disengaging at the first point 314 and engaging at the second point 316, forming a sealed area 322, allowing the fluid 324 to hydrostatically escape between the points 314, 316.

摘要： A fuel pump for a direct injection internal combustion engine having a housing defining a pump chamber 38. Driven and idler toothed gears 44, 46 are rotatably mounted within the pump chamber 38 so that the driven and idler gears 44, 46 are in mesh with each other at a predetermined location in the pump chamber 38. A fluid inlet 26 is formed through the housing 36 and open to an inlet subchamber 52 in the pump chamber 38. A fluid outlet 54 is also formed through the housing 36 and open to an outlet subchamber 56 in the pump chamber. A pressure relief passageway 60 fluidly connects the inlet subchamber 52 to the outlet subchamber 56 and a valve 62 is disposed in series with the pressure relief passageway 60. A control circuit 23 controls the actuation of the valve 62 to control the pump pressure at the pump outlet.

摘要： A gear pump (20) comprises a drive gear (24) being mounted for rotation about a first axis and having a plurality of gear teeth (25) at a radially outer location. A driven gear (26) is mounted for rotation about a second axis, and having a plurality of teeth (27) at a radially outer location. The drive gear teeth engage the driven gear teeth at a contact face to cause the driven gear to rotate. Slots (50) are formed in the contact face of one of the drive and driven gear teeth.
