Definitions

  • Figs. 5 and 6 are transverse sections on lines 5 5 and 6-6 of Fig. 1, respectively.
  • Spacer 33 also has a longitudinal groove 33, engaged by the stem of a set-screw 37, ⁇ and a chamber 33", connected with a circular groove 105 33s, leading through a duct 38 into a cavity wherein is screwed a pressure lubricator.
  • said cavity may be stopped by a plug 39, the lubricant being supplied under through a duct connected for instance with lio a pressure lubricating pipe from the engine on which the pump is mounted.
  • spider 50 remains tightly pressed against the drum and the cage.
  • the delivery pressure increases, said pressurebeing transmitted to the inside of the elastic piston through holes 50c and 44C.
  • it 110 overcomes the tension of elastic piston 43 and of spring 51, spider 50 recedes from its seat, and a by-pass flow of variable amount takes place, parallel with the movable wall or spider inside the very chamber where the volumetric variation is produced.
