Abstract (en)
[origin: EP2388421A2] The unit (1) has a piston (3) arranged in a housing (2) and impacted with a spring (5) i.e. shutter spring. The piston co-acts with a driven shaft (4) for opening and/or closing a leaf. A pressure balance device (8) is arranged in the housing that is filled with hydraulic fluid (9). The pressure balance device has an input cabinet, whose inner space stands in contact with an inner space of the housing of the unit via a collet. The collet passes till to a volume middle point of the cabinet, and is closed via a stopper such that vacuum filling of the unit is enabled.
