Abstract

A disc assembly for a fluid flow control device includes an annular disc member, a disc holder, a relief bore, at least one branch passage, and an annular recess formed in the disc holder. The relief bore is formed in a first side of the disc holder along a central axis of the assembly. The annular recess is formed in the first side of the disc holder and is disposed coaxially with the relief bore for accommodating at least a portion of the annular disc member. The at least one branch passage is formed in the disc holder and provides fluid communication between the relief bore and the annular recess such that during use pressurized fluid that accumulates in the annular recess between the disc member and the disc holder can be relieved through the relief bore via the branch passage.
