Abstract
A composite bearing cylinder includes an inner bearing surface having a resin matrix with fumed silica therein and having a filament material helically embedded in the resin matrix, a layer of the resin matrix being located at the inner bearing surface, the fumed silica in the resin matrix thereby contributing to the wear resistance of the inner bearing surface.
Claims22
A combination piston and composite bearing cylinder comprising,
- a continuous inner bearing surface,
- the inner bearing surface defining a primary bearing direction along an axis of the cylinder,
- a piston having a surface for movement along the continuous inner bearing surface in the primary bearing direction,
- a resin matrix composed of a resin material having fumed silica therein, the resin material at least partially at the inner bearing surface, the fumed silica providing wear resistance to the continuous inner bearing surface, and
- a substantially continuous filament material embedded within the resin matrix, the substantially continuous filament material including a round cross-section, the substantially continuous filament material forming a plurality of substantially rounded filament surfaces at said continuous inner bearing surface.

A combination piston and composite bearing cylinder comprising,
- a composite bearing cylinder comprising:
- a continuous inner bearing surface;
- the inner bearing surface defining a primary bearing direction along an axis of the cylinder;
- a resin matrix composed of a resin material having fumed silica therein, the resin material at least partially at the inner bearing surface, the fumed silica providing wear resistance to the continuous inner bearing surface;

A combination piston and composite bearing cylinder comprising, a composite bearing cylinder comprising:
- a continuous inner bearing surface;
- an outer surface radially opposed to said continuous inner bearing surface;
- a resin matrix composed of a resin material having fumed silica therein providing hardness and wear resistance to said continuous inner bearing surface, said resin material at least partially comprising said inner bearing surface;
- and
- a substantially continuous filament material embedded within said resin matrix, said substantially continuous filament material including a cross-section having a circular filament surface, said substantially continuous filament material forming a plurality of circular filaments at said continuous inner bearing surface, said plurality of circular filaments at said continuous inner bearing surface and a portion of said resin material forming said continuous inner bearing surface, and
- a piston having a surface for movement along the continuous inner bearing surface in the primary bearing direction.
