Abstract
A head assembly for a drilling operation. The assembly includes a retractor case comprising a retractor pin slot. The assembly includes a body that comprises a body pin slot, wherein an interior space of the body is configured to receive the retractor case. The assembly includes a latch ear coupled to the body, wherein at least a portion of the latch ear extends outward relative to the body. The assembly includes an expansion block at least partially disposed within an interior space defined by the retractor case. The assembly is such that a position of the expansion block along a longitudinal axis of the assembly determines whether the latch ear is in an extended position or a retracted position relative to the body sidewall.
Claims21
An assembly for performing a drilling operation in a substrate, the assembly comprising:
- a body comprising a sidewall, wherein the sidewall defines a hollow interior comprising a fluid chamber, and wherein the hollow interior is aligned with a longitudinal axis of the assembly;
- a fluid retention piston disposed within the fluid chamber, wherein the fluid retention piston comprises a fluid port enabling a fluid to pass through the fluid retention piston;
- and
- a valve assembly disposed within the fluid retention piston, wherein the valve assembly comprises:
- a valve bushing comprising a sidewall that defines a bushing interior space;
- a valve ball;
- and
- a valve spring;
- wherein the valve assembly is in a closed configuration when the valve ball is at least partially disposed within the bushing interior space and prevents fluid from flowing through the bushing interior space.
