Master cylinder.

摘要

A master cylinder having a pressure cylinder (l) and a pressure-generating piston (6) movable therein, the cylinder being closely surrounded over part of its length by a separate reinforcing member (l4) in the form of a sleeve which acts to prevent significant expansion of the cylinder under the effect of internally applied pressure. In the example shown, the pressure cylinder forms part of an integral moulding which includes a fluid reservoir (2).
