Abstract (en)
[origin: US4690035A] An emergency drain device for pneumatic cylinders which is integrated in an orientatable connection fixed directly to the cylinder body and comprises a valve which closes an orifice of the bolt of the connection, going to the atmosphere, when a control pressure is applied to the head of the bolt. This device is advantageously used in installations where a general isolating switch, controlled by the same control pressure, connects the general distribution line to the atmosphere, for example in the case of an emergency, when said pressure disappears.
