The invention relates to an internal gear machine () having a housing () which forms a cavity () in which an internally toothed ring gear () and an externally toothed pinion () are arranged, the toothings () of which are in meshing engagement with one another in certain regions and the axes of rotation () of which run parallel to and spaced apart from one another, wherein at least one filler piece () rests against the first and second toothings (), which divides the cavity () into two fluidically separate regions. It is provided that the toothing () is designed as helical toothing or arrow toothing.

Internal gear machine with helical toothing

A hydraulic unit () for providing a pressurized hydraulic fluid for driving a coupled hydraulic actuator (), comprising a motor () arranged in a motor housing (), a hydraulic accumulator () arranged in an accumulator housing, a hydraulic pump () arranged in a hydraulic housing and a hydraulic block (), wherein the motor housing (), the accumulator housing and the hydraulic housing are fluidically connected to one another. It is provided that at least one main flow connection between the hydraulic pump () and the actuator () is guided through at least one channel () of the motor housing ().

Hydraulic unit

The application relates to an internal gear machine for reversing duty having a housing with a chamber, in the chamber there are disposed an externally toothed pinion and an internally toothed ring gear, which mesh with one another, the rotational axes of which run parallel to and spaced apart from one another. The chamber in the housing is axially bounded and is connected via pressure pockets provided in the housing to pressure connections in the internal gear machine. According to the invention, a switching valve is arranged in each connection between the pressure pockets and the pressure connections or compression spaces, which valve opens or closes the connection.
