Claim 0:
1. A pulsation valve system comprising:
a mandrel operably coupled to a rotor of a pulsation assembly, the mandrel comprising a mandrel bore defined through a first mandrel end and along a longitudinal axis of the mandrel, and one or more bypass bores defined through the mandrel and in communication with the mandrel bore;
an oscillating valve head attachable to the mandrel and rotatable with the mandrel, the oscillating valve head including an oscillating valve bore defined therethrough and parallel with a longitudinal axis of the oscillating valve head; and
a stationary valve head positioned adjacent and stationary with respect to the oscillating valve head, the stationary valve head including a stationary valve bore defined therethrough and parallel with a longitudinal axis of the stationary valve head;
a spring located in the mandrel bore;
a piston slidably received in the mandrel bore in operable contact with the spring;
wherein the oscillating valve bore being alignable with the stationary valve bore at a predetermined rotational position;
wherein the mandrel bore is in communication with a first oscillating valve central bore of the oscillating valve head;
wherein the piston being configured to block an entrance of the bypass bores from inside the mandrel bore at a first position and to allow fluid to flow into the bypass bores from inside the mandrel bore at a second position.
