Quick connect coupling for a hydraulic control system including integral damper

摘要

A quick connect coupling for use in a hydraulic clutch control system including a hydraulic master cylinder and a hydraulic slave cylinder. One ofthe coupler members (44; 80 Fig. 5) of the quick connect coupling includes a central axial passage (54d; 80c Fig 5) defining an inlet at one end of the passage and including a diaphragm (72; 86 Fig. 5) positioned at the other end of the passage at right angles to the passage and in fluid communication with fluid flowing through the passage. The passage further includes a radial passage portion (54i; 80h Fig. 5) communicating with the central passage and extending to a fluid outlet for the coupler member. Hydraulic fluid flowing through the coupler member communicates with an inboard face (72c; 86b Fig. 5) of the diaphragm so that the diaphragm functions to attenuate pulsations in the hydraulic fluid and preclude transmission of the pulsations in the system to the clutch pedal.
