摘要
A control valve assembly includes a body including a mud flow passage having a mud flow inlet and a mud flow outlet, a magnetic plunger slidingly mounted within the body, and a solenoid mounted at the body about the magnetic plunger. The solenoid is selectively activated to shift the magnetic plunger between a first position covering the mud flow outlet and a second position exposing the mud flow outlet allowing a pulse of mud to flow through the mud flow passage.
