Title:
How to use a hydraulic pressure supplying device, an oil pressure system, and it
Document Type and Number:
Japanese Patent JP6196819
Kind Code:
B2
Abstract:
A hydraulic feed device may include a pendulum-slide cell pump having an internal rotor drivingly connected to an external rotor via pendulum slides. A hydraulic positioning device may have a positioning element for changing an eccentricity between the internal rotor and the external rotor. The positioning element may be preloaded by a spring device for setting a maximum eccentricity. The positioning device may have a first pressure adjusting and a second pressure adjusting chamber for adjusting the positioning element. The first pressure adjusting chamber may be permanently hydraulically connected to a pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device. The second pressure adjusting chamber may be controlled via a control valve and hydraulically connected to the pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device.
