Etymology: < air n.¹ + chamber n.

1664 N. Henshaw Aero-Chalinos v. 85 Working gently with the Bellows, you may either charge, or discharge..the Air-Chamber at your pleasure, and consequently, obtain an Air in it, of what rarity or density you please.

1775 N. D. Falck Philos. Diss. Diving Vessel 4 Midship in this sloop, a little towards the bow..was built the air-chamber; its dimensions in the clear twelve feet long, nine feet broad, and eight feet deep.

1846 Cumberland (Maryland) Alleganian 13 Mar. 2/1 The Suction is flexible..and has an air-chamber..attached, so as to keep up a constant stream.

1852 Christian Inquirer (N.Y.) 14 Aug. 3/3 in Amer. Lit. (1990) 62 307 The air-chamber can be placed on any of the seats now in use... A steamboat may thus be furnished with a large number of life-preservers.

1873 E. Atkinson tr. A. Ganot Elem. Treat. Physics §206 The fire engine is a force pump in which a steady jet is obtained by the aid of an air-chamber.

1908 H. G. Wells War in Air viii. §1 The airship was remarkably simple to construct: given the air-chamber material, the engines, [etc.]..it was really not more complicated..than an ordinary wooden boat had been..before.

1911 C. J. Lynde Home Waterworks vii. 91 The air chamber is placed on the discharge pipe to prevent strains and to keep up a continuous supply of water.

1968 Times 24 Sept. (Spec. Rep. Electr.) p. viii/3 Pressure is maintained..in the air chamber by a flexible skirt suspended from the side and end girders of the transporter.

1994 J. Johnson Whitewater Rafting Man. viii. 204 The buoyancy of the submerged air chamber may cause the raft to pop to the surface.

2. Biology. In an animal or plant: any chamber or cavity filled with air or gas; esp. each of the gas-filled chambers in the shell of a cephalopod.
