Abstract
A muscle-powered diving equipment comprising a pump worn by the diver, which is operated by the diver's legs by means of a belt arrangement and foot loops attached thereto. When the diver's legs are extended, air is sucked in through a tube whose end is attached to a floating buoy. When the diver's legs are bent, the aspirated air is compressed by the pressure of the surrounding water and can be breathed in by the diver through a breathing tube. The exhaled air escapes through an expiration valve into the water.
