Abstract
Aspects of the disclosure can relate to a displacement assembly that includes a housing that defines a passage to be in fluid communication with a pressurized fluid supply proximate to a first end of the passage. The displacement assembly also includes a displacement mechanism slidably coupled with the housing to reciprocate in the passage from a first orientation where the displacement mechanism is proximate to the first end of the passage toward a second orientation where the displacement mechanism is proximate to a second end of the passage opposite the first end. The displacement mechanism and the housing define a seal for preventing pressurized fluid from the pressurized fluid supply from migrating through the passage when the displacement mechanism is in the first orientation. The displacement mechanism and the housing allow pressurized fluid to migrate through the passage when the displacement mechanism is in the second orientation.
