Abstract
A quick connect coupling for use in a hydraulic clutch control system including a hydraulic master cylinder and a hydraulic slave cylinder. One of the coupler members of the quick connect coupling includes a central axial passage defining an inlet at one end of the passage and including a diaphragm positioned at the other end of the passage at right angles to the passage in fluid communication with fluid flowing through the passage. The passage further includes a radial passage portion communicating with the central passage and extending to a fluid port for the coupler member. Hydraulic fluid flowing through the coupler member communicates with an inboard face of the diaphragm so that the diaphragm functions to attenuate pulsations in the hydraulic fluid and preclude transmission of the pulsations rearwardly in the system to the clutch pedal.
