ABSTRACT:
A high pressure valve assembly (10) comprising a valve sleeve (14) and a valve body (16) slidably mounted in the valve sleeve (14) is disclosed, the valve body (16) and valve sleeve (14) each having first ends (18, 56) and second ends (20, 58). A sidewall (22) extends between the valve sleeve first end (18) and second end (20) which sidewall (22) has an inner surface (24) and an outer surface (26) and at least one opening (30) therethrough. The sidewall (22) also includes at least one channel (40) having a first end (42) facing the inner surface (24) at a first location closer to the first valve sleeve end (18) than to the second valve sleeve end (20) and a second end (44) facing the inner surface (24) at a second location closer to the second valve sleeve end (20) than to the first valve sleeve end (18). A method of using the valve assembly (10) is also disclosed.
