摘要： The invention relates to a locking arrangement which can be released from its locking state by means of a pressurized fluid, and to a nozzle through which pressurized fluid can be supplied to the locking arrangement to release the same. The locking arrangement includes a latch bolt (6) which is connected to a plunger (5) arranged for axial movement in a chamber (4), the plunger dividing the chamber into two, substantially pressure-tight part chambers (4a, 4b). The plunger (5) is biassed towards its locking position by a spring means (8) and can be moved axially to a lock release position, against the force of the spring means by a pressurized fluid, e.g. compressed air, lead into the one part chamber (4a). To this end, the aforesaid one part chamber (4a) communicates via an opening (12) in a chamber wall (13) with a fore-chamber (14) which is located externally of the chamber (4) and which communicates with the other partchamber (4b) through a second opening (15) in the aforesaid chamber wall (13). The opposite external wall (17) of the fore-chamber (14) is provided with a third through-passing opening (16) which is located opposite the aforesaid second opening (15). The nozzle (18) according to the invention is formed so as to enable it to be inserted into the aforementioned second and third openings (15, 16), so as to seal the same with its outer surfaces. The nozzle (18) has a first, internal channel (27,23,24) through which pressure fluid can be passed into the fore-chamber (14) from a pressure-fluid line connected to the nozzle, and a second, internal channel (20,21) through which the other part chamber (4b) is placed in communication with the surroundings.
