results which lifts the first valve body 30 off from the first valve seat 33 so that the first fluid flow path 16 is opened eventually the stop 39 on the first valve body 30 impinges on the sidewall of the control chamber 21 at the same time impinging on a protruding portion 57 of the second valve body 50 so that the latter is kept in the opened position if the pressure at the first connection 14 now falls the corresponding pressure on the first valve body 30 eventually no longer suffices to overcome the biasing force of the first and the second spring 34 54 as a result the first and the second valve body 30 50 move towards their valves seats 33 53 the second valve seat 53 closing first so that the second fluid flow path 17 is interrupted as a result the fall in pressure at the restrictor 36 ceases so that the pressure at the first working connection 14 acts both on the annular surface 41 and on the larger end face 42 on the first valve body 30 the first valve body 30 is thereby pressed against the first valve seat 33 so that the first fluid flow path 16 is closed the valve 10 is then back in the initial position described above fig2 shows a rough diagrammatic sectional representation of a valve 10 u2032 according to a second embodiment of the disclosure the second embodiment is of identical design to the first embodiment except for the.
