Claim 0:
1. A pulsation valve system for providing oscillating fluid flow to a downhole tool, the pulsation valve system comprising:
a valve mandrel including a shaft section, and a mandrel cavity defined through a first mandrel end and into the valve mandrel along a longitudinal axis of the valve mandrel;
an oscillating valve head including an oscillating valve bore defined therethrough and parallel with a longitudinal axis of the oscillating valve head, the oscillating valve head being attachable to the shaft section of the valve mandrel so that the oscillating valve head rotates with the valve mandrel;
a stationary valve head positioned adjacent and stationary with respect to the oscillating valve head, the stationary valve head including a stationary valve central bore and a stationary valve bore each being defined therethrough and parallel with a longitudinal axis of the stationary valve head;
wherein the shaft section of the valve mandrel is receivable through the stationary valve central bore and secured in the oscillating valve central bore defined in the oscillating valve head;
wherein the oscillating valve bore being cyclically allignable with the stationary valve bore at a predetermined rotational position based on rotation of a rotor so that the fluid flow cyclically passes through the stationary valve bore and the oscillating valve bore.
