Patent number: 11202977Abstract: As shown for example in FIG. (5), the strainer (13) has a body (2) that defines a plurality of inlet holes (3). Each of the inlet holes (3) is in fluid communication with a hollow internal chamber. In use, liquid is sucked through the holes (3), thereby straining out larger contaminants such as rocks and stones, into the hollow internal chamber and then out the outlet. The majority of the strainer (13), is formed from a resilient deformable material that allows opposed sides of the internal chamber to be brought into contact with each other in response to the application of a compressive force. Once the force is no longer being applied, the resilience of the material allows the body (2) to resiliently return to substantially its pre-deformation shape.Type: GrantFiled: March 8, 2016Date of Patent: December 21, 2021Assignee: Jets Innovations Pty LtdInventor: Tom Monaghan
