Claim Text:
1. An apparatus for use in a wellbore, comprising: a housing having a longitudinal axis for flow of fluid along the longitudinal axis; and a valve body having a first end and a second end, the valve body being movable in the housing along the longitudinal axis, the valve body including a main passage oriented along the longitudinal axis that allows a fluid supplied to the first end of the valve body to flow through the main passage into a flow area in the housing and a weep hole that allows the fluid supplied to the first end of the valve body to flow through the weep hole to enter the valve body, the valve body attaining a first position when a pressure of the fluid supplied to the first end is below a threshold rate, the first position allowing fluid to pass into the valve body via the main passage and the flow area and the valve body attaining a second position when the pressure of the fluid supplied to the first end is above the threshold rate, the second position preventing the flow of the fluid through the main passage while allowing the fluid to flow through the weep hole.
