    摘要: Poor inlet suction characteristics in regenerative pumps may be avoided in a construction including a housing (10) having an impeller receiving cavity (20) with a circular impeller (22) therein. Channel-like annular grooves (32, 34) are disposed in the housing (10) and open to the cavity (20) at sides (36, 38) of the impeller (22). An outlet seal (63) is located in each of the grooves (32, 34) and outlet ports (62) opening to the grooves (32, 34) are located just upstream of the outlet seal (63). Peripheral recesses (42, 44) are located in the impeller sides (36, 38) and have radially inner extremities (59) located radially inward of the channels (32, 34). A plurality of blades (52) are mounted to the impeller (22) within the recesses (42, 44) around the periphery thereof and have radially inner edges (54) spaced from the radially inner recess extremities (59) while being isolated from recirculation within the channels ( 32, 34). An inlet port (70) is disposed in the housing (10) and is located between the radially inner extremity of the grooves (42, 44) and the radially inner edges (54) of the blades (52).

    摘要: A gearbox system includes a gearbox having integrated therein a pump system, a plurality of fluid passages and a clutch control system. The pump system is in fluid communication with the clutch control system via the fluid passages to flow at least one pressurized stream. A first pressurized stream controls a first pressure-responsive device included in the clutch control system. The gearbox system further includes a hydro-mechanical control unit (HMCU) in fluid communication with the gearbox to receive a second pressurized stream and to generate at least one actuator control stream. The actuator control stream controls an actuator integrated in the gearbox.
