Abstract
A choke for fluid connection between a manifold and a pump. The choke includes a fluid passage having an inlet, a contraction portion, a throat, an expansion portion, and an outlet. The inlet has a first diameter and the outlet has a second diameter. The throat is substantially cylindrical, having a third diameter that is substantially less than the first and second diameters. The contraction portion connects the inlet and the throat and gradually decreases from the first diameter to the third diameter along a longitudinal axis of the fluid passage. The expansion portion connects the throat and the outlet and includes a substantially cylindrical chamber having the second diameter.
