Parker’s reservoir type master cylinders are designed for long, reliable service life and feature a reservoir integrated into the housing. This eliminates the need for a separate, remotely mounted reservoir.
Master cylinders are located in the cockpit on each of the pilot’s rudder pedals. They are used to turn a force into a pressure to actuate the brakes on an aircraft. By integrating the reservoir directly into the master cylinder housing, Parker has eliminated the need for a separate, remotely mounted reservoir.
There are several advantages to this fewer fittings translates into fewer possible leak paths and the elimination of the need to find a remote location for a reservoir in a space-limited aircraft. This also means there are fewer parts to inspect and maintain, no need for a hydraulic line between the remote reservoir and the master cylinder, and weight savings.
Parker offers a version with a reservoir designed into the cylinder. It eliminates the need for a remote reservoir located in the firewall area, giving easier control over the system and less line from the brake assembly.
The reservoir capacity ranges from 2 to 3.4 cubic inches with strokes from 1.2 to 1.75 inches. Total volumetric output is 0.36 to 0.77 cubic inches. Ports are 1/8-27 NPT thread, which is common in the general aviation market.
APPLICATIONS: General aviation, light jets, turboprop passenger and cargo aircraft.
