HOLDING APPARATUS OF DOUBLE DOOR |
摘要 |
A holding installation with an integrated closing sequence regulation is described for double doors comprising a leading door which is the first to close and a trailing door which then closes. The hydraulic door closer associated with the trailing door is provided with a signal generating device which is actuated in dependence on the piston position, and with an additional return flow passage for hydraulic fluid. The signal generating device controls the solenoid valve which holds the leading door by preventing the movement of hydraulic fluid contained in the door closer for the leading door, thus preventing movement of the associated piston. |
