ABSTRACT:
An improved double wall cylinder includes a neck which extends along an axis generally coincident with the longitudinal axis of the cylinder. This neck supports an outer wall and an inner wall and includes a first passage and a second passage for providing fluid communication between the cylinder and a remote control unit. The outer and inner tubular walls are preferably formed of commonly available tubing and the manufactured cost of the cylinder may be reduced by the fact that one of the tubular walls is devoid of threads, apertures and other machined portions. If the end gland is removed for service, the inner wall is frictionally retained in position while the piston assembly is withdrawn. The inner wall may then be removed, leaving the outer wall attached to the neck by a threaded connection. Risk of accidential loss of parts is thereby reduced. The cylinder is configured for use with a mounting plate of the type having a pair of spaced, outwardly extending hollow lugs. The cylinder includes a unique neck which allows the cylinder to be installed to or removed from the lugs for service without disturbing the position of the mounting plate or the lugs.
