ABSTRACT:
A valve assembly that includes a valve body defining a fluid passage. First and second ends of the fluid passage define first and second ports for fluid flow. A spring and piston are located in the fluid passage. The piston has a travel length extending between first and second positions with a third position located therebetween. The spring biases the piston from the first toward the third position and is located outside the axial piston passage. The piston at least partially defines a first, second and at least one third opening. The first opening defines a variable constriction which increases in size as the piston moves from the first to third positions. The piston end wall defines the second opening and the piston sidewall defines the third openings. Movement of the piston from the third to second position exposes the third openings increasing the area of the second port.
