Hydromechanical massaging device

DETAILED DESCRIPTION OF THE DRAWING FIG.
1 shows the massaging device provided with an external housing made of two half-shells 1 and 2 which may be plastic mouldings and are assembled together by any suitable means such as by welding, glueing, fastener screws, etc .

which may optionally allow a dismantling of the device for maintenance if needed.
The device is preferably provided with a hollow handle containing an inlet duct 3 converging from its inlet end 4 towards a distributor 5, the cross-section of which is much smaller than the inlet cross-section.
Inlet 4 may be connected by any suitable means to a flexible hose which may in turn be connected to the water mains, for instance to a shower circuit in a bathroom.
The outline of distributor 5 comprises a first arcuate sidewall 16 which closely surrounds the tips of the vanes 22 of the turbine wheel 6, at first, and then gradually diverges away from the turbine wheel beyond a point 23 located approximately 75.
degree.
away from the upstream end of the distributor.
This extension of sidewall 16 remains concave throughout and its distal end 24 joins one lateral edge of a passage opening into an outlet duct 18.
The upper side of duct 18 is lined by a concave surface 20 formed in the upper half-shell 1 of the housing.
Duct 18 is further confined by a transverse wall 27 formed in the lower half-shell 2 of the housing, this wall 27 forming part of an enclosure 25 inside which is contained the reducing gear connecting the shaft 26 of the turbine wheel 6 to the output shaft 11.
Enclosure 25 is further confined on its upper side by a platen 17 forming the bottom of the turbine chamber and on its lower side by the lower half-shell 2 of the external housing.
Inorder to avoid any accidental turbulence in the flow of water which will normally be gliding smoothly along the concave surface 20 of duct 18, such turbulence being liable to cause a slit projection of water when the device is being held upside down or in a vertical position, there is further provided a small deflector 19 which extends beyond the downstream edge 28 of transverse wall 27
