Patent ID: 10737877

Abstract:
A blast aerator (20) having a discharge end (23) connected internally to a rigid output tube (24) includes a retrofittable aerator control module (15) that internally, sealingly interacts with the output tube (24). A tank discharge pipe (28) directs air blasts into an external application. The aerator control module (15) comprises an external actuator (30) that controls a reciprocating plunger assembly (50) that interacts with an internal plunger seat (77) to block or unblock air discharge. The plunger seat adaptor assembly (70) fitted to the aerator output tube (24) comprises a resilient plunger seat (77), that is blocked or unblocked by a plunger element (52) controlled by a slidable piston (38) that is pneumatically displaceable between tank-filling and tank discharge positions within the actuator (30). The plunger seat adaptor assembly (70) mechanically compensates for output tube misalignment to insure proper sealing. Operational air pathways pneumatically control piston movements without springs.
