Abstract:
A friction engagement element and lubricating system comprising:a case; a friction engagement element, housed within said case, for engaging a rotatable member with said case, the friction engagement element including a hub connected to the rotatable member, at least one friction member centered on an axis and disposed between the hub and the case, and an oil passage; a discharge opening of the oil passage located radially inward of and spaced from the friction member, on a first axial side of the friction member, for supplying a lubricant from the case onto the friction member; and a weir member positioned at a second axial side of the friction member, opposite said first axial side, said weir member extending radially inward from a radially outer portion, located radially outward of said friction member, to its radially innermost edge which is located radially inward of said friction member and which is spaced from said hub to define a gap therebetween, said gap restricting escape of the lubricant axially between the hub and the friction member.
