Abstract

Lydkilde for generering av lavfrekvent undervannslyd, omfattende to symmetriske stempler (1,2) l en luftfylt sylinder (3), anordnet langs samme akse, koblet enten direkte til to lineære motorer eller, ved hjelp av stempelstenger (10,11), til to Justerbare eksenter- skiver (4,5) som l sin tur er festet til drivakslingen (6) til en rotasjonsmotor (4), der stempelbevegelsens amplityde og raseforskjellen mellom de to stemplene (1,2) kan variere, samt midler (7,8,9) for trykk- kompensasjon i sylinderen og eventuelt fjerning av inntrengt vann.Sound source for generating low-frequency underwater sound, comprising two symmetrical pistons (1,2) in an air-filled cylinder (3), arranged along the same axis, connected either directly to two linear motors or, by means of piston rods (10,11), to two Adjustable eccentric washers (4,5) which in turn are attached to the drive shaft (6) of a rotary motor (4), where the amplitude of the piston movement and the difference in race between the two pistons (1,2) can vary, as well as means (7,8 , 9) for pressure compensation in the cylinder and possible removal of penetrated water.
