mechanism.
According to the present invention, there is provided a regulator for diving comprising a basic structure adapted to be kept in substantially air-tight condition so long as a diver is actually using it, a pressure-controllable air supply mechanism housed in the basic structure to supply the diver with air, a mouthpiece connected to the basic structure and a check valve provided within the basic structure so as to be operated between opened and closed positions.
The air supply mechanism further has a tubular housing connected to an air supply source lying outside the basic structure, a pressure reducing valve provided within the housing and a deflector mounted on the housing and acting upon the air, and the housing is formed in its peripheral wall extending in front of thepressure reducing valve as viewed in a direction of the air flow with an air outlet port adapted to supply the mouthpiece with the air having its pressure reduced by the pressure reducing valve and the deflector covers the housing from the outside with a gap between the deflector and the peripheral wall, on one hand, and covers the air outlet port from immediately above as viewed in a radial direction of the housing.
The present invention includes preferred embodiments as follow:
The deflector has a tubular portion adapted to be telescopically mounted around the housing and an extension extending outwardly from the tubular portion in the radial direction, the tubular portion being formed in the vicinity of a proximal end of the extension with a through-hole communicating with the
