Abstract
A fishing jar includes an outer housing, a mandrel positioned at least partially within the outer housing and having a fish end, an anvil coupled to or integral with the mandrel, a hammer coupled to or integral with the outer housing, and a triggering mechanism partitioning a first chamber and a second chamber, the first and second chambers separated axially apart and in fluid communication via the triggering mechanism. The triggering mechanism is configured to permit hydraulic fluid to flow from the first chamber to the second chamber at a first rate in response to pressing the outer housing to move toward the fish end of the mandrel during a downstroke of the outer housing, until the outer housing reaches a trigger position, and then permit the hydraulic fluid to flow from the first chamber to the second chamber at a second rate until the hammer impacts the anvil.
