A housing of a fluid energy machine which extends along a longitudinal axis, includes a housing casing which extends axially, a housing cover for closing off a housing opening axially on the face side of the housing casing, an annular insert which extends in the housing in a circumferential direction and which bears against the housing casing and against the housing cover, a first seal between the housing cover and the housing casing. To save radial installation space, a second seal is between the housing casing and the annular insert, and a third seal is between the housing cover and the annular insert.

Housing of a fluid energy machine

A divisible housing of a fluid machine for a transmission to be received in the divisible housing is provided. The transmission provided for receiving in the divisible housing includes a large wheel and at least two pinion shafts which are in engagement with the large wheel. The divisible housing includes a first housing element and a second housing element which is connected to the first housing element via a parting joint. The at least two pinion shafts may be received in the parting joint. The parting joint includes a parting joint step, the at least two pinion shafts being receivable in the parting joint on both sides of the parting joint step.

A collecting chamber of a flow machine which expands in the direction of circumference, including at least one outer shell part and a contour insert is provided. The contour insert is provided with a groove which extends in the circumferential direction and is preferably configured as a helical spiral. The contour insert, is cut from a whole unit and is delimited at one end in the circumferential direction by a bent edge so that the flow losses are minimized during the passage from the collecting chamber into a subsequent diffuser.

Collecting chamber and production process

An electromotive actuator for deflecting a motor vehicle part includes a rotatable component and a non-rotatable component. The rotatable component can be driven by an electric motor in such a way that it can be moved linearly relative to the non-rotatable component between a first position and a second position. In order to create a compact adjustment device, the two components of the actuator are configured respectively as a threaded spindle and a threaded nut, whereby the rotatable component (threaded spindle or threaded nut) is non-rotatably connected to the rotor of the electric motor and can act directly or indirectly on the vehicle part that is to be deflected.

Electromotive actuator for deflecting a motor vehicle part

An electromotive actuator for deflecting a mechanical part, comprising a rotatable component and a non-rotatable component of a deflection gear, whereby the rotatable component can be driven by an electric motor in such a way that it can be moved linearly relative to the non-rotatable component between a first position and a second position. The two components of the actuator are constituents of a ball-ramp adjustment device, whereby a rotatable component of the ball-ramp adjustment device is non-rotatably connected to the rotor of the electric motor and acts directly or indirectly on the mechanical part that is to be deflected.
