Device for damping vibrations in a hydraulic force-transmission circuit, in particular for hydraulic clutch control

Device (1) for damping hydraulic vibrations, capable of being incorporated into a hydraulic circuit forming a hydraulic clutch control, the device (1) comprising: - a body (6), and - an insert (8) received at least partially in the body (6), the device (1) extending along a longitudinal axis (X) between an upstream end (10) and a downstream end (11) defined by the direction of circulation of a fluid in said hydraulic circuit, the device (1) defining: - a first path (35) provided in the insert (8), in the form of a screw (16) whose axis is the longitudinal axis (X) of the device, said path (35) allowing the fluid present at the level of the upstream end (10) to reach the downstream end (11) by traveling a first length in the device (1), and - at least one second path (26, 50) allowing the fluid present at the level of the upstream end (10) to reach the downstream end (11) by traveling a second length in the device (1) and without traveling the first path (35), the first length being greater than the second length, the device (1) being configured such that, in the device, the fluid continuously approaches the downstream end (11) during its path from the upstream end (10).
