Abstract
A hose fitting includes a fitting body, having an inlet opening, an expansion opening, and an outlet opening. An expansion disc is coupled with the expansion opening and is formed from a deformably resilient material. A portion of the expansion disc expands outwardly from the fitting body, when pressure within the fitting body increases, increasing a volume of the fitting body. The expansion disc contracts, as the pressure within the fitting body reduces. The expansion disc may be removably coupled with the expansion opening using an expansion nut, having an open center portion.
Claims15
A hose fitting, comprising:
- a fitting body, having an inlet opening, an expansion opening, an outlet opening, and an interior portion that defines a fluid pathway, which extends between and in fluid communication with the inlet opening, expansion opening, and the outlet opening;
- an expansion disc, operatively coupled with the expansion opening, such that the expansion disc defines a portion of an exterior wall of the hose fitting;
- the expansion disc being formed from a deformably resilient material such that, as a pressure within the fluid pathway increases from a base pressure, a portion of the expansion disc expands outwardly from the fitting body, increasing a volume of the fluid pathway from a base volume, wherein the expansion disc is removably coupled with the expansion opening;
- and
- an expansion nut removably coupled with the expansion opening such that the expansion disc is secured between the expansion opening and the expansion nut, wherein the expansion nut has an open central portion that is shaped to allow a portion of the expansion disc to expand into and at least partially through the open central portion.
A hose fitting, comprising:
- a fitting body, having an inlet opening, an expansion opening, an outlet opening, and an interior portion that defines a fluid pathway, which extends between and in fluid communication with the inlet opening, expansion opening, and the outlet opening;
- an expansion disc, removably, operatively coupled with the expansion opening such that the expansion disc defines a portion of an exterior wall of the hose fitting;
- the expansion disc being formed from an elastomeric material such that, as a pressure within the fluid pathway increases from a base pressure, a portion of the expansion disc expands outwardly from the fitting body, increasing a volume of the fluid pathway from a base volume, and the expansion disc contracts, as the pressure within the fluid pathway reduces toward the base pressure, reducing the volume of the fluid pathway toward the base volume;
- and
- an expansion nut removably coupled with the expansion opening such that the expansion disc is secured between the expansion opening and the expansion nut;
- the expansion nut having an open central portion that penetrates opposite end portions of the expansion nut and is shaped to allow a portion of the expansion disc to expand into and at least partially through the open central portion so that at least a portion of the expansion disc extends out of the expansion nut.
