Title: REFLEXIVE VALVE PRESERVATION AND ACTUATION SYSTEM AND METHODS
Abstract:
Embodiments of the present disclosure include a valve assembly including a supply housing (64) with a first bore (72) and an injectable housing (66) coupled to the supply housing (64) with a second bore (74). The valve assembly further includes a piston (70) extending through at least a portion of the first and second bores (72, 74), the piston (70) being reciprocable axially along a longitudinal axis (76). The valve assembly also includes a first inlet (80) at a first end (78) of the supply housing (64) for directing a working fluid toward a first end (110) of the piston (70). The valve assembly includes a second inlet (84) extending through the injectable housing (66) toward a cavity (94) that receives an injectable material (152). The valve assembly also includes a second outlet (86) at a second end (88) of the injectable housing (66) that directs the injectable material (152) out of the injectable housing (66) as the piston (70) moves axially along the longitudinal axis (76).
