Rotary piston pump e.g. high pressure gear pump for conveying fluid e.g. petrol to internal combustion engine of motor car, has outlet channels opened in diverting workspace for discharging to-be-conveyed fluid from diverting workspace

摘要

The pump (1) has a running wheel with conveying elements whose rotational motion is carried out around a rotational axis (26). A working chamber in the running wheel is divided into an inflow workspace and a diverting workspace. An inflow duct (22) is opened in the inflow workspace for introduction of the to-be-conveyed fluid in the inflow workspace. The outlet channels (24) are opened in the diverting workspace for discharging the to-be-conveyed fluid from the diverting workspace. The housing (8) is provided with two separate outlet channels in the diverting workspace. An independent claim is included for high-pressure injection system.
