Combined relief - and surge protection apparatus for pressurizible operating medium reservoir is in operation means supply systems hydrodynamic machines

摘要

The present invention relates to a combined relief - and surge protection apparatus for pressurizible operating medium reservoir is in operation means supply systems hydrodynamic machines- with a housing;- with a with the interior of the operation means container and an inlet chamber can be coupled with an outlet chamber can be coupled with a relief chamber;- with a relief valve, comprising a displaceable in the housing is mounted in a valve element and a valve seat arranged in the housing in a stationary manner, and the valve seat is arranged in such a way that the latter, in cooperation with the valve member the connection between the inlet chamber and the outlet chamber blocks;- with a the valve member associated actuating device;- with a surge protection device, comprising a positive surge plate, which is connected with the valve member on a guide element can be guided outside of the housing, in which the guide element at its end facing away from the valve component, a stop for the movement of the positive surge plate has;- with a seat on the housing, which, in combination with the positive surge plate closes the inlet chamber, wherein between the positive surge plate and guide element is provided at least one throttle point.
