Abstract
A main stage in-line pressure control cartridge. The cartridge selectively controls flow in-line in the same direction. The cartridge is mounted inside a body and has a sliding control sleeve that can expose radial holes in the poppet to an open position and to seal the radial holes in a closed position. A retainer collar is located on the opposite end of the control sleeve. Flow is permitted in a direction from the control sleeve to the retainer collar. The body has a mating recess to accommodate a step in the retainer collar which prevents movement of the retainer collar towards the control sleeve. When fluid pressure is applied to the retainer collar in the direction of the control sleeve, the step in the retainer collar presses against the body thereby preventing the fluid pressure from moving the retainer collar.
