    Patent number: 4512934
    Abstract: An air bubble hydromassaging apparatus having a blower housed in a control unit, a bubble grid adapted to be placed in a bathtub, and air tubing enclosing a check valve to connect the control unit to the bubble grid. The control unit is provided with a bushing type compressed air outlet and the bubble grid is provided with a bushing type compressed air inlet. The air hose has a connector fitting on each end by which it is detachably and airtightly connected to the compressed air outlet of the control unit at one end and to the compressed air inlet of the bubble grid at the other end. A check valve built into the connector fitting serves to obstruct passage through the connector fitting when the blower is inoperative and opens to permit passage through the connector fitting when the blower is operative.
