Self adjusting valve catch with valve seating control

A valve seating device, comprising:

• a housing having a bore, a bore side wall, and side wall openings;
• an outer piston slidably disposed in the bore, the outer piston having an internal hydraulic passage, an internal chamber defined by an outer piston side wall, outer piston bottom wall, and an internal orifice connecting the internal hydraulic passage and the internal chamber;
• a catch piston slidably disposed in the outer piston, the catch piston having an extension extending from the catch piston, and the catch piston extension having a shoulder with a flat face adapted to seat against the outer piston bottom wall and a cone-shaped extension extending from a part of the flat face into the outer piston internal orifice;
• a cap disposed at an upper portion of the outer piston;
• and
• a catch piston spring disposed between the catch piston and the cap.

• a cylindrically shaped catch piston slidably disposed in the outer piston internal chamber, the catch piston having a hollow interior portion and the catch piston having an extension extending from the catch piston;
• the catch piston extension having a shoulder with a flat face adapted to seat against the outer piston bottom wall and a cone-shaped extension extending from the flat face into the entirety of the outer piston internal orifice;
• a cap disposed at an upper portion of the outer piston;
• and
• a catch piston spring disposed between the catch piston and the cap.
