Abstract
Hydraulic systems generally comprise expansion hose lines and other damping elements which are provided with one or several serially connected hose chambers according to the generated pressure pulsation. The damping measures of the inventive hydraulic system are initiated according to the prevailing pressure during operation thereof. The aim of the invention is to keep the loss of pressure low and save a significant amount of energy during continuous operations. Said aim is achieved by a direct line connection between the source of pressure and the user, which bypasses the dampers. Said bypass line is blocked by a valve when the pressure in the system increases.
Claims17
A pressurized fluid power transmission system, comprising:
- a pressure source and a load;
- and
- interposed between the pressure source and the load, a damping device which also comprises at least two channels arranged parallel to each other, said channels being controlled by a valve means which effects the flow distribution to the channels as a function of the pressure at a selected point of the power transmission system.
