Abstract

A pressure wave motor that may be a fluid driven device with a continuous reciprocating driven member, the sole moving part, for connection into an appropriate non compressable fluid supply system that sustains pressure waves and that allows the reciprocating driven member to generate a usable harmonic pressure wave for use in sustaining continuous reciprocation of the driven member along with fluid flow. The pressure wave motor is driven solely by the fluid supply input fluid which is a liquid and the forces the input fluid generated by continuous reciprocation of the driven member for producing work without additional moving parts. The fluid supply system may be a normal household water supply system. The fluid driven device can produce a pulsating fluid output that may be used for cleaning and massaging. The fluid driven device includes a driven member cavity, the inlet connected to the cavity, a main outlet connected to the member cavity, a second outlet connected to the member cavity, and a control system. The pressure wave motor may be self-starting and the second outlet includes a variable fluid volume chamber between the member cavity and the second outlet. A variable valve may be used at the outlets to vary the rate of reciprocation of the driven member.

Dependent claims

A device for producing pressure pulses of liquid comprising:

(a) a housing having a liquid inlet, a liquid outlet, and a chamber therebetween;
(b) said chamber includes an inline valve device in said housing comprising a body means having a piston chamber portion and a valve seat portion,
said inline valve device with an inlet connected to the liquid inlet, an outlet connected to the liquid outlet and said valve seat portion therebetween;
a valve device having a valve head cooperating with the outlet side of said valve seat portion for controlling flow between said inlet and said outlet and a piston portion on the inlet side of said valve seat portion connected to said valve head reciprocating in said piston chamber portion;
said piston portion having a larger area than said valve head so that inlet pressure on the side of said piston portion facing said valve seat portion acts in a direction to close said inline valve device;
restricted passage means communicating inlet pressure from one side to the other side of said piston portion so as to aid in operation of said inline valve device;
restriction means communicating said piston chamber portion on said other side of said piston portion with atmosphere;
and
a closed air chamber communicating with said piston chamber portion on said other side of the piston;
said air chamber, said restricted passage means, said restriction means and said valve device so dimensioned as to cause oscillation of said valve device and thus a pulsating flow of liquid at said liquid outlet in response to connection to a source of pressurized liquid at said liquid inlet.
