Claims
- 1. A fluid oscillator for producing pulsations in a flow of fluid comprising:
- (a) a housing defining a fluid inlet channel, first and second similar fluid outlet channels each of which exhibits less resistance to fluid flow than the inlet channel, a valve chamber located between and communicating with said channels, the valve chamber including a surface defining first and second valve seats where the respective outlet channels meet the valve chamber, said inlet channel being adapted to be connected to a supply of fluid under pressure to direct this flow generally towards said surface and said outlet channels communicating with atmosphere;
- (b) a freely movable spherical valve element contained loosely in said valve chamber and dimensioned to alternately engage said valve seats and seal the respective outlet channels, the valve seats being positioned adjacent one another and opposite said inlet channel whereby, with the valve element located on a first of the valve seats, fluid flowing towards the second of the outlet channels will entrap the valve element and move the element with this fluid on to said second valve seat whereupon fluid will then flow towards the first of the valve seats and then entrap the valve element to return the valve element to the first valve seat, such movements of the element being repeated as long as fluid flows so that fluid leaving by way of the first and second outlet channels will pulsate.
- 2. A fluid oscillator as claimed in claim 1 wherein said surface is conical.
- 3. A fluid oscillator as claimed in claim 1 wherein said surface is wedge-shaped.
- 4. A fluid oscillator as claimed in claim 1 wherein the geometrical configuration of the outlet channels is adjustable to vary the frequency of pulsations of fluid flow.
- 5. A fluid oscillator as claimed in claim 2 in which the conical surface and the positions of the valve seats are symmetrical about the centre line of the inlet channel.
