摘要： A pressure difference of liquid is generated between an upper end and a lower end of a thread groove by the action of a thread groove pump formed between the thread groove and a lower end wall portion of a rotating rotor shaft. As a result, liquid of a bottom space is sucked up and passes through a hollow hole and is discharged to the outside of the rotor shaft through communication holes. The discharged liquid passes through the inside of a hub of a rotating body and reaches an extension member where it is sprayed radially in the form of droplets from a protrusion. The droplets are received by a partition wall. Due to the presence of a protrusion in an upper portion of the partition wall, the droplets cannot cross over the partition wall. The accumulated liquid drops through a communication hole to the bottom space.

摘要： A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder. The first radial shoulder and the second radial shoulder each include at least one slot. An axial separation between the first radial shoulder and the second radial shoulder defines an axial distance SA along an axis of rotation. The at least one slot defines a lowermost radial dimension SR from the axis of rotation. A ratio of SR/SA is 0.25-0.77.

摘要： A valve (11) for controlling the flow of a drilling fluid through a down-hole tool (10) positionable in a wellbore penetrating a subterranean formation. The down-hole tool has a housing with a drilling motor therein and a drill bit (1) at an end thereof. The drilling motor (9) has a housing with a rotor (206) rotationally movable in a rotor channel (204) as the drilling fluid passes through a rotor channel between the housing and the rotor. The rotor has a bypass channel therethrough for bypassing a portion of the drilling fluid therethrough. The valve includes a valve plate positionable upstream of the motor. The valve plate (200) has at least one flow passage (226) and at least one bypass passage (220) therethrough. The flow passage is in fluid communication with the rotor channel for passing the drilling fluid therethrough. The bypass passage is in selective fluid communication with the bypass channel when the rotor rotates about the housing and moves the bypass channel into alignment with at least a portion of the bypass passage for bypassing a portion of the drilling fluid therethrough whereby a hammering effect is generated on the bit.
