Definitions

  • first gutter 22 Secured to the same side of the side plate 15 is a first gutter 22 which consists of an annular plate pressed to offset an outer flange 22a which is attached to the side plate.
  • the groove 20 ends within this gutter so that any liquid passing inwardly along the groove 20 enters the gutter 22.
  • the gutter 22 is connected by a tube 23 extending between the side plates 1.5, 16 to a second gutter 24 of similar design on the side plate 16.
  • a tubular scoop member 25 mounted on the housing 10 extends into the gutter 24 and, as shown, projects in a direction opposite the direction in which the gutter moves locally during rotation of the rotor 14.
  • the scoop member 25 is connected to an auxiliary outlet 26.
