Abstract
A miniaturized emitter, penetrably mounted within the wall of a conduit having a fluid to be dispensed, emits a constant volume output flow irrespective of changes in fluid pressure within the conduit. An annular flange laterally biased by an inscribed annular pressure chamber sealingly seats the emitter against the wall of the conduit. A pair of downwardly depending skirts having striae disposed on facing surfaces, in combination with the extant pressure on the opposing sides of the skirts, regulate the passage size within the emitter to maintain constant the rate of output fluid flow regardless of pressure variations within the conduit.
Claims24
An emitter for discharging fluid from a fluid conveying conduit at a constant rate despite changes in pressure within the conduit, said emitter being penetratingly insertable within an aperture in the wall of the conduit, said emitter comprising:
- a. a head including a discharge outlet having an axis normal to the wall of the conduit for conveying fluid from within the conduit and through the wall of the conduit;
- b. an annular channel disposed about said head for receivingly engaging the edge of the aperture in the wall of the conduit;
- c. an annular flange disposed adjacent said channel for contactingly engaging the inner wall surface of the conduit adjacent the aperture to maintain said emitter in place;
- and
- d. bias means extending from said head interior to the conduit for maintaining a constant rate of fluid flow through said discharge outlet despite variations in pressure within the conduit, said bias means being disposed in axial alignment with said discharge outlet, said bias means including a pair of opposed skirts longitudinally separable from one another for defining a single passageway for the flow of fluid to said discharge outlet, said passageway being in general axial alignment with said discharge outlet;
- whereby, said emitter is penetratingly mountable within an aperture in the conduit to maintain a constant rate of fluid discharge from the conduit despite variations in fluid pressure within the conduit.
An emitter for discharging fluid from a fluid conveying conduit at a constant rate despite changes in pressure within the conduit, said emitter being penetratingly insertable within an aperture in the wall of the conduit, said emitter comprising:
- a. a head having a discharge outlet for conveying fluid from within the conduit and through the wall of the conduit;
- b. an annular channel disposed about said head for receivingly engaging the edge of the aperture in the wall of the conduit;
- c. an annular flange disposed adjacent said channel for contactingly engaging the inner wall surface of the conduit adjacent the aperture to maintain said emitter in place;
- d. a pressure chamber comprising a downwardly opening annular depression inscribed by said channel and disposed within said head for urging radial expansion of said annular flange, said pressure chamber being responsive to the fluid pressure within the conduit;
- e. bias means extending from said head interior to the conduit for maintaining a constant rate of fluid flow through said discharge outlet despite variations in pressure within the conduit, said bias means including a pair of opposed skirts separable from one another for defining a single passageway for the flow of fluid to said discharge outlet and further defining an orifice at the junction of said passageway and said discharge outlet;
- and
- f. striae disposed upon the surface of at least one of said pair of skirts forming the passageway;
- whereby, said emitter is penetratingly mountable within an aperture in the conduit to maintain a constant rate of fluid discharge from the conduit despite variations in fluid pressure within the conduit.
An emitter for discharging fluid from a fluid conveying conduit at a constant rate despite changes in pressure within the conduit, said emitter being penetratingly insertable within an aperture in the wall of the conduit, said emitter comprising:
- a. a head having a discharge outlet for conveying fluid from within the conduit and through the wall of the conduit;
- b. an annular channel disposed about said head for receivingly engaging the edge of the aperture in the wall of the conduit;
- c. an annular flange disposed adjacent said channel for contactingly engaging the inner wall surface of the conduit adjacent the aperture to maintain said emitter in place, a radial surface of said annular flange being an extension of a side wall of said annular channel;
- d. bias means extending from said head interior to the conduit for maintaining a constant rate of fluid flow through said discharge outlet despite variations in pressure within the conduit, said bias means including a pair of opposed skirts separable from one another for defining a single passageway for the flow of fluid to said discharge outlet;
- whereby, said emitter is penetratingly mountable within an aperture in the conduit to maintain a constant rate of fluid discharge from the conduit despite variations in fluid pressure within the conduit.

- and
- d. bias means extending from said head interior to the conduit for maintaining a constant rate of fluid flow through said discharge outlet despite variations in pressure within the conduit, said bias means including a pair of opposed skirts separable from one another for defining a single passageway for the flow of fluid to said discharge outlet, each skirt of said pair of skirts being non-planar;
- whereby, said emitter is penetratingly mountable within an aperture in the conduit to maintain a constant rate of fluid discharge from the conduit despite variations in fluid pressure within the conduit.
