Abstract
A core barrel head assembly having a longitudinal axis can comprise an elongate tube body having an outer surface, an interior cavity, a proximal end, and a distal end. The elongate tube body can define a helical groove that extends from the interior cavity to the outer surface of the elongate tube body. The helical groove can be configured to allow the elongate tube body to elastically extend and compress. The elongate tube body can define at least one aperture that extends between the interior cavity and the outer surface. The core barrel head assembly can further comprise a valve body that is attached to the elongate tube body and is movable with respect to the proximal end of the elongate tube along the longitudinal axis, as the elongate tube body compresses. When sufficiently compressed, the valve body restricts flow through the at least one aperture.
