Abstract
A piston for a wind instrument includes a one-piece body, the one-piece body defining a plurality of ports and one or more windways each connecting at least a subset of the plurality of ports. The plurality of ports and the one or more windways are formed by processing a single piece of a material to remove a portion of the material from the single piece. The single piece of the material can be a cylindrical rod of the material. The one-piece body can be made of aluminum, an aluminum alloy, brass, a nickel-copper alloy, or stainless steel. The surface of the piston can be hard coat anodized and/or polytetrafluoroethylene (PTFE) sealed.
Claims34
A method of making a piston for a wind instrument, the method comprising:
- removing a first portion of material from a single piece of the material to form a plurality of ports and one or more windways each connecting at least a subset of the plurality of ports.
A piston for a wind instrument, the piston comprising:
- a one-piece body, the one-piece body defining:
- a plurality of ports;
- and
- one or more windways each connecting at least a subset of the plurality of ports,
- wherein the plurality of ports and the one or more windways are formed by processing a single piece of a material to remove a portion of the material from the single piece.
A wind instrument comprising:
- one or more tubes configured to transport air moved by a user of the wind instrument;
- a valve casing, wherein a side wall of the valve casing comprises one or more openings aligned with the one or more tubes;
- and
- a piston disposed within the valve casing, the piston comprising:
- a one-piece body, the one-piece body defining:
- a plurality of ports, and
- one or more windways each connecting at least a subset of the plurality of ports,
- wherein the plurality of ports and the one or more windways are formed by processing a single piece of a material to remove a portion of the material from the single piece.
