Abstract:
1. A well tool for use with a subterranean well, the well tool comprising: a flow passage extending longitudinally through the well tool; an internal chamber containing a dielectric fluid, wherein the chamber is in fluid communication with a source of the dielectric fluid via a conduit extending to a remote location, and wherein a line extends through the conduit to an actuator in the chamber; and a flow path extending between the internal chamber and the flow passage, the flow path including first, second, and third longitudinal flow path sections, the first longitudinal flow path section being connected to a first end of the second longitudinal flow path section, and the third longitudinal flow path section being connected to a second end of the second longitudinal flow path section opposite the first end, whereby communication between the internal chamber and the flow passage via the flow path reverses longitudinal direction at least twice.
