Abstract
A method for assembling an actuating ram of air bleed valves, which ram is placed between low pressure and high pressure compressors of a turbomachine, the ram including a piston rod surrounded by a spacer extending from the piston cylinder and configured to be connected to an end of the transmission mechanism linked to the bleed valves, the method including: deploying the piston rod such that it projects from the spacer; connecting the projecting piston rod to the end of the transmission mechanism; retracting the piston rod to bring the cylinder closer to the case wall; and attaching the spacer to the case wall.

A method for assembling an actuating ram of at least one air bleed valve placed between a low pressure compressor and a high pressure compressor of a turbomachine, the ram including a cylinder configured to be attached to a case wall from which projects an end of a transmission mechanism linked to the air bleed valve, the cylinder being extended by a spacer being used to attach the cylinder to the case wall, and including a piston rod surrounded by the spacer and configured to be connected to the end of the transmission mechanism, the method comprising:
- deploying the piston rod to project from the spacer;
- connecting the projecting piston rod to the end of the transmission mechanism projecting from the case wall on a side of the ram;
- retracting the piston rod to bring the cylinder closer to the case wall;
- and
- attaching the spacer to the case wall.
An actuating ram of at least one air bleed valve configured to be placed between a low pressure compressor and a high pressure compressor of a turbomachine, the ram comprising:
- a cylinder extended by a spacer being used to attach the ram to a case wall of the turbomachine;
- and
- a piston rod surrounded by the spacer and configured to be connected to an end of the transmission mechanism;
- wherein the spacer is free of side openings.
