Patent number: 9879528Abstract: An actuator for a mud pulse telemetry tool. The actuator includes a solenoid-based servo valve with a coil shaft responsive to data transmitted by a data processor. The coil shaft is movable between an extended position and a retracted position. Movement of the coil shaft to the extended position moves a poppet to close a servo orifice thereby preventing mud flow to a main mud pulse valve of the mud pulse telemetry tool. Movement of the coil shaft to the retracted position moves the poppet to open the servo orifice thereby allowing mud flow to actuate the main mud pulse valve. The poppet is connected to a poppet shaft and the poppet shaft cooperates with the coil shaft in a slide hammer mechanism to amplify force provided by the coil shaft against the poppet shaft with linear movement of the coil shaft to the extended position and to the retracted position.Type: GrantFiled: December 12, 2016Date of Patent: January 30, 2018Assignee: EXTENSIVE ENERGY TECHNOLOGIES PARTNERSHIPInventors: F.
