ABSTRACT:
An aspirator device is placed in an hydraulic circuit that incorporates one or more hydraulically actuated solenoid valves. The aspirator comprises a cylindrical body having a through bore for the passage of pressurized oil therethrough and a branch bore, in communication with the main bore, connected to the pilot drain of the valve. The pressurized passage of the oil in the through bore causes a negative pressure at the branch bore and the pilot drain.
