Fluid system with internal filter

Abstract

The invention is a fluid system with an internal filter assembly that prevents particulate from moving between portions of the fluid system. The internal filter assembly is located within a fluid path extending between a particle source, such as a textile tensile member, and a portion of the fluid system that may be affected by particulates from the particle source, such as a value. The fluid system, and particularly the internal filter assembly, has applicability to articles of footwear, for example.

Description

technical field [0001] The present invention relates to a fluid system. In particular, the present invention relates to an inner filter assembly for a fluid system for restricting the movement of particles within the fluid system. Background technique [0002] Athletic footwear generally consists of two basic components, the upper and the sole structure. The upper structure is used to stably and comfortably accommodate the foot and is typically foam, leather, and textile materials that are stitched or bonded together. The sole structure generally includes multiple layers, which are referred to as the inner sole, the midsole and the outer sole. An insole is usually an elongated part located near the foot, with an insole to enhance the comfort of the shoe. The midsole forms the middle layer of the sole and typically includes a resilient foam material, such as polyurethane or ethylene-vinyl acetate, to relieve pressure and absorb energy when the shoe makes contact with the g...
