Abstract

A torsional vibration damper (1) comprises an annular driven hub member (2) and an outer annular inertia member (3) capable of limited rotational movement relative thereto. The damper (1) has diametrically opposed variable volume pumping chamber sets (16) defined by blades (11) of the inertia member being received in cavities in the hub member. Relative movement of said hub and inertia members in a first direction decreases the volume of one of said chambers (16) and increases the volume of the other whereas relative movement in the opposite direction causing a reverse variation in the volume of the chambers (16). The variable volume chambers (16) are connected, in use, to a source of damping fluid which is pressurised by the relative movement. Each blade (11) has a planar base surface that is adjacent a planar bottom surface of each cavity. The planar surfaces enable easier and cheaper manufacturing.
