Abstract
A downhole assembly and method are provided for selective activation of a motor in a drilling string. A rotor in a Moineau-principle motor is provided with a fluid passage therethrough and a catch that can receive and retain a blocking implement. A driveshaft is operably connected, for example using universal joints, to the rotor and a first valve component. The driveshaft is effectively supported by a thrust transmission assembly comprising a thrust unit and hanger resting on a spring so that the first valve component is not in contact with a second valve component. When a blocking implement is in place, drilling fluid activates the motor and also increases pressure on the rotor, causing the thrust transmission assembly to move the first valve component down into contact with the second valve component.
