Double, which is coupled to the shut-off valve for switchable power sources with a direct drive for hydraulic systems

摘要

In a hydraulic circuit which, by means of a switchable hydraulic force source with a direct drive is operated, the two inlet - / outlet - connections for the introduction of a pumped hydraulic fluid in a volume - inlet branch and for pumping hydraulic fluid from a volume - outlet branch of the hydraulic circuit, the relative to the direction of the flux of the hydraulic fluid in the hydraulic circuit be determined, and the has a container with hydraulic fluid,a dual, which is coupled to the shut-off valve improvement comprising, in combination therewitha) a distributor, the with the corresponding inlet - / outlet - connection of the switchable hydraulic force source with a direct drive is hydraulically coupled and the one movement by gear, which defines a means by means of gear - outflow, which is coupled hydraulically to the container, wherein each end of the movement by gear has an angled annular valve seat, which is subdivided into a distributor channel opens with a larger diameter,b) a shut-off valve ball, the inside each of the large distributor channel at each end of the movement is arranged by means of gear,c) a movement of rod with a larger length and a smaller perimeter diameter than the or of the of the movement by gear,..
