ABSTRACT:
A valve for selectively controlling flow within a fluid line between a relatively low capillary flow rate and a flushing flow. A flush valve (10) comprises a base (14) and a cover (16) that secures an elastomeric membrane (18) in place over a flow path (32) formed in the base. The flow path includes an inlet passage (34) connected in fluid communication to an outlet passage (50) by a capillary groove (38). The membrane seals over the capillary groove to define a capillary passage (48), which restricts fluid flow through the flush valve to the capillary flow rate. A user may selectively enable the relatively greater fluid flow through the device by deforming the membrane away from the capillary groove, thereby creating a relatively larger flushing flow passage (66). The flushing flow of fluid through the region of the capillary groove serves to carry away any obstruction that may be present in the groove or downstream of the flush valve.
