Hydraulic clutch release mechanism

Abstract

A hydraulic clutch release mechanism has a clutch pedal-operated master cylinder connected with the clutch release member (such as a fork or a bearing) by way of a conduit or by way of a slave cylinder and a conduit. The sealing but separable connection between at least one of the cylinders and the respective conduit comprises a T-shaped fitting having a first section sealingly connected with an end portion of the respective conduit and a second section coupled to the housing of the at least one cylinder by snap action. The fitting further carries a relief valve which opens when the pressure of hydraulic fluid in a plenum chamber of the at least one cylinder rises to a preselected value. The fitting and/or the housing and/or the body of the valve and/or the end portion of the conduit consists of or contains a suitable plastic material, such as polyamide.
