20100275773 | PUMP LINER RETENTION DEVICE - A method and apparatus for maintaining a seal between a cylinder and a fluid manifold for a reciprocating force delivery device is disclosed. A cylinder retention assembly comprises a rotatable member with a variable topography surface. The rotatable member is disposed against a stop extending outwardly from the cylinder, and is fastened to the fluid manifold by a locking ring. When rotated, the rotatable member produces an axial force on the locking ring and the cylinder, urging the cylinder against the fluid manifold. The cylinder retention assembly may be used in reciprocating pumps and compressors. | 11-04-2010 |
20100275774 | BIAXIAL ALIGNMENT ASSEMBLY FOR FORCE DELIVERY DEVICE - A method and apparatus for accommodating mis-alignment of a piston rod in a reciprocating force delivery device is provided. A piston rod is coupled to a piston by a pivot bearing disposed around the piston rod inside the piston. The pivot bearing contacts an internal surface of the piston and provides a biaxial pivot point, which may also be triaxial, for the piston rod inside the piston. The pivot point is located near the centroid of the piston, enabling forces not aligned with the axis of the piston to be decoupled into axial and transverse components. The force decoupling avoids rotational moment on the piston, minimizing the possibility of metal-to-metal contact between components of the piston and the cylinder liner. | 11-04-2010 |
20100278661 | VALVE COVER ASSEMBLY - A method and apparatus for sealing an opening of a fluid manifold is provided. A grooved sealing member, having compliant members disposed in the grooves, is seated in the opening. A retention member is coupled to the fluid manifold by tensile members such as bolts. One or more compression members fit between the retention member and the sealing member, and a cap fits over the sealing member to secure the one or more compression members. The cap is fastened to the sealing member. When pressure is applied inside the fluid manifold, the force generated thereby is transmitted by the sealing member through the one or more compression members, and the retention member, to the tensile members, which absorb and equalize the force around the sealing member. | 11-04-2010 |

20090294118 | METHOD AND APPARATUS FOR USE IN A WELLBORE - An improved hanger assembly and method for its use is described herein, along with various examples of alternative constructions for the hangar assembly. Also described are examples of new tool strings having improved capabilities that are facilitated as a result of use of the described hanger assemblies. The described hanger includes a deformable section having improved engagement capabilities. In preferred examples, these improved engagement capabilities are achieved by use of a first deformable section of the hanger that extends radially outwardly from the remainder of the hangar body, when the hanger is set; and a contact member that is further urged radially outwardly relative to that deformable section when the hanger is set. | 12-03-2009 |

20130124166 | MODELING OPERATION OF A TOOL IN A WELLBORE - In modeling operation of a well tool in applying a force to a device in a well, a computing system receives inputs representing a plurality of geometric characteristics of the well tool. The computing system also receives inputs representing a plurality of geometric characteristics of the well. The computing system determines based on the geometric characteristics of the well tool and the well, a predicted reaction force on a portion of the well tool that affects operation of the well tool in applying force to the device. The predicted reaction force is due to contact between a surface associated with the well tool and a surface of the well. | 05-16-2013 |
20140048288 | HYDROSTATIC PRESSURE ACTUATED STROKE AMPLIFIER FOR DOWNHOLE FORCE GENERATOR - Methods and apparatus are presented for a hybrid downhole force generator (DFG) using a stroke amplifier driven by hydrostatic pressure for a low-force, long-stroke portion of setting a downhole tool and a DFG powered shaft for a high-force, short-stroke portion of setting the tool. The stroke amplifier has a piston slidable in a housing, movable in response to hydrostatic pressure. The DFG powered shaft is connected to the piston via one-way slips which allow relative motion of the piston and shaft in one direction. The amplifier housing is connected to the DFG housing. In use, the DFG shaft is powered by a power supply, such as an electric motor, etc. The shaft is powered to shear a shearing mechanism, freeing the piston to move in response to the hydrostatic pressure. | 02-20-2014 |
