Abstract

An actuator arrangement, having a drive for providing a rotational movement about an axis of rotation and which includes an actuator housing whose outer surface extends with a curved profiling along the axis of rotation and which delimits a working space, in which a working element is rotatably accommodated, which includes a drive shaft which penetrates a front surface of the actuator housing, wherein the actuator housing is penetrated by a working port, which is designed for a connection of the working space with a valve arrangement, and with a valve arrangement, which is designed for a provision of a fluid flow at the working port and which includes a valve module, which is accommodated in a valve shaft of a valve housing and which has a fluid port, wherein the valve housing extends with a profiling in the form of a circular ring section along the axis of rotation.

First claim

What is claimed is:

1. An actuator arrangement for providing a movement, with a drive, which is designed for a conversion of a fluid flow into a rotational movement about an axis of rotation and which comprises an actuator housing whose outer surface extends with a curved profiling along the axis of rotation and which delimits a working space, in which a working element is rotatably accommodated, which comprises a drive shaft arranged coaxially with the axis of rotation, which penetrates a front surface of the actuator housing, wherein the actuator housing is penetrated by a working port, which is designed for a connection of the working space with the valve arrangement, and with a valve arrangement, which is designed for a provision of a fluid flow at the working port, wherein the valve arrangement comprises a valve module, which is accommodated in a valve shaft of a valve housing, wherein the valve module has a fluid port and wherein the valve housing extends with a profiling in the form of a circular ring section along the axis of rotation.

2. The actuator arrangement according to claim 1 , wherein the valve housing has a first, concave profiled wall section facing the actuator housing and a second, convex profiled wall section facing away from the actuator housing.

3. The actuator assembly according to claim 2 , wherein at least one of the first wall section and the second wall section is profiled in the form of a circular arc section.

4. The actuator assembly according to claim 1 , wherein the actuator housing has a first working port and a second working port, and wherein the valve housing comprises a first valve shaft with a first valve module accommodated therein and a second valve shaft with a second valve module accommodated therein, said first valve module having associated therewith a first fluid port connected to said first working port and said second valve module having associated therewith a second fluid port connected to said second working port.

5. The actuator arrangement according to claim 4 , wherein the first fluid port of the first valve module accommodated in the valve housing is connected with a third output port of a third valve module, and wherein the second fluid port of the second valve module is connected with a fourth output port of a fourth valve module, and wherein the third valve module and the fourth valve module are accommodated in a third valve shaft and in a fourth valve shaft of a second valve housing.

6. The actuator arrangement according to claim 1 , wherein the two working ports are aligned on an axial surface of the actuator housing, and wherein the fluid ports of the respective valve modules are aligned on an axial surface of the valve housing, and wherein the working ports and the fluid ports are each connected with fluid channels, which are formed in a distributor plate, which abuts the axial surfaces of the actuator housing and the valve housing.

7. The actuator arrangement according to claim 6 , wherein the valve housings abut in each case with an axial surface on an opposite axial surface of the distributor plate, and wherein the distributor plate for fixing the valve housings is formed on the actuator housing.

8. The actuator arrangement according to claim 6 , wherein the distributor plate or a distribution block associated with the distributor plate has a centrally arranged shaft recess which is provided on a circumferential inner wall with an annular channel, which is connected with a supply channel formed in the distribution plate, and wherein the drive shaft is penetrated along the axis of rotation by a fluid bore, which opens out separated by an end section of the drive shaft into one radial bore, which is arranged opposite the annular channel.

9. The actuator arrangement according to claim 1 , wherein the working element is designed as a rotary vane and divides the working space into a first subspace and into a second subspace in conjunction with a sealing element extending along the axis of rotation, which is fixed in the working space, whereby a working port is assigned to the first subspace and the second subspace.

10. The actuator arrangement according to claim 1 , wherein the drive is designed as a hinge for the pivotable coupling of a first arm section with a second arm section of a pivoting arrangement.
