Abstract
A hydraulic oscillating motor which has at least two working chambers which are coupled via pressure lines to a device for pressure compensation. A first working chamber is connected to a first pressure line and a second working chamber is connected to a second pressure line. The motor further has a device for pressure compensation with a first compensating cylinder and a second compensating cylinder. Each of the compensating cylinders has in each case one compensating volume and in each case one elastic force store for delimiting the respective compensating volume. The compensating volume of the first compensating cylinder is connected to the first pressure line, and the compensating volume of the second compensating cylinder is connected to the second pressure line.
