| Abstract: | A control valve arrangement includes a valve body with a filling chamber
with a filling hole. A filling valve is arranged in the filling chamber
for opening or closing a first fluid communication controlling filling of
a first control chamber, the filling valve having a filling valve member
with a moving valve seat, the filling valve member being normally biased
open by a first spring. A control valve opens and closes a second fluid
communication for controlling the emptying of the first control chamber,
the control valve being normally biased closed by a second spring. A plug
is arranged in the valve body for closing the filling chamber, the plug
being provided with an opening which cooperates with the moving valve
seat, the opening defining the first fluid communication between the
filling chamber and the first control chamber. |
