Abstract
A drip irrigation emitter is provided extending between first and second longitudinal ends. The emitter has an outer side for attaching to a pipe that is laterally bound between first and second longitudinal edges. The outer side has a flow path and an exit pool, and at least a section of the flow path extends downstream along the first edge and at least a portion of the exit pool is formed between the section of the flow path and the second edge.
Claims20
A drip irrigation emitter extending between first and second longitudinal ends, the emitter comprising:
- a first member having an outer side for attaching to a pipe, and an inner side;
- the outer side comprising a peripheral surface comprising first and second longitudinal edges connected to first and second lateral edges, a longitudinal axis equally spaced between the first and second longitudinal edges and a lateral axis perpendicular to the longitudinal axis and equally spaced between the first and second lateral edges,
- the outer side comprising an exit pool, an outlet to the exit pool connecting the inner side to the outer side, and a pressure reducing flow path;
- the flow path comprising a first section which extends longitudinally along substantially all of the first longitudinal edge and is spaced apart from the longitudinal axis,
- the flow path having a flow path beginning and a flow path end, each provided with a bore connecting the outer side to the inner side;
- a second member extending between the first and second longitudinal ends and overlying the inner side of the first member;
- and
- a membrane interposed between the first and second members to provide flow regulation,
- wherein
- the exit pool on the outer side is asymmetrically arranged with respect to the longitudinal axis;
- and
- the emitter is asymmetric along the longitudinal axis, to assist in correctly orienting the emitter when or before being fitted to an irrigation pipe.
A drip irrigation emitter extending between first and second longitudinal ends, the emitter comprising:
- a first member having an outer side for attaching to a pipe, and an inner side;
- the outer side comprising a peripheral surface comprising first and second longitudinal edges connected to first and second lateral edges, a longitudinal axis equally spaced between the first and second longitudinal edges and a lateral axis perpendicular to the longitudinal axis and equally spaced between the first and second lateral edges,
- the outer side comprising an exit pool, an outlet to the exit pool connecting the inner side to the outer side, and a pressure reducing flow path;
- the flow path comprising a first section which extends longitudinally along substantially all of the first longitudinal edge and is spaced apart from the longitudinal axis,
- the flow path having a flow path beginning and a flow path end, each provided with a bore connecting the outer side to the inner side;
- a second member extending between the first and second longitudinal ends and overlying the inner side of the first member;
- and
- a membrane interposed between the first and second members to provide flow regulation,
- wherein:
- the exit pool on the outer side is asymmetrically arranged with respect to the longitudinal axis;
- and
- the second member includes a longitudinally extending step such that the second member has an asymmetric shape in a view taken along the longitudinal axis.
