Hydraulic drive with fast stroke and load stroke
Abstract:
An autarkic hydraulic linear drive with a hydraulic arrangement and a method for operating the same. The hydraulic arrangement a pump unit, an equalizing reservoir, a load switching valve configured to switch between a fast extension and a load extension, and a hysteresis circuit. The hysteresis circuit is configured for triggering a first switching process of the load switching valve at a first control pressure and a second switching process of the load switching valve at a second control pressure that is different than the first control pressure.
