Abstract: A balancer of an engine includes a rod and a balancer piston. A first end portion of the rod includes a joining portion which is arranged to be joined to a crankshaft of the engine at a position that is eccentric relative to a rotation axis of the crankshaft. A second end portion of the rod is arranged to reciprocate inside a cylinder according to a rotation of the crankshaft. The balancer piston is fixed to the second end portion of the rod. The balancer piston is arranged to reciprocate inside the cylinder, while rocking between a contact state in which the balancer piston is in contact with an inner wall surface of the cylinder and a non-contact state in which the balancer piston is separated from the inner wall surface. The balancer piston includes a cylindrical outer peripheral portion that is curved so as to swell toward the inner wall surface. The outer peripheral portion is arranged such that lines of intersection with planes perpendicular or substantially perpendicular to a central axis of the balancer piston define circles. The outer peripheral portion includes a contact start portion which is arranged to come into contact first with the inner wall surface when the balancer piston switches from the non-contact state to the contact state. A distance from a center of a maximum outer diameter circle with the largest radius among the circles to the contact start portion is larger than the radius of the maximum outer diameter circle.

Abstract: In a wobble press with a first wobbling die-half and an axially parallel moving second half-die, the wobbling motion is generated by a plurality of hydraulically actuated working pistons cyclically engaging with the wobbling half-die and by means of the elimination of centrifugal forces by a counterweight (G) connected to the wobbling half-die, the precise guiding of the die-halves by a centering disk and the avoidance of a mechanical drive by using a multiple-pistons pump and a hydraulic control system for the working pistons, it is possible to reduce undesirable rotary forces, vibration, friction and heat generation in such a way that substantially higher wobble frequencies and shorter processing times are attained at lower cost while maintaining the geometrical wobble effect owing to the higher wobble frequency, with a simple and rapidly acting control of the extent and form of the wobbling movement even during operation, thus making it possible to preselect the most suitable pressing program.

Abstract: A compact well jack is particularly suitable for reciprocating a long stroke rod pump and in situations wherein horizontal area around the well head is limited. The pump jack has a frame with elongated guides, a lifting bar slidably disposed between the guides, a horizontal slot in the lifting bar, pulleys carrying an endless belt having a stud affixed opposite to a counter weight and extending into the slot such that rotation of the pulleys vertically reciprocates the lifting bar and sucker rod string while the stud moves horizontally within the slot.

Abstract: An oscillatory pumping system of the type having sheave chains wound in opposing directions over a mandrel, one sheave chain connecting to a rod string of a well and another supporting a counterbalance, is improved to include both rate and position sensors which, through a logic system control the application and reversal of power. The system is further improved by selection of geometry and in engagement features such that upon full playout of either chain the time of stroke reversal is shortened. This counterbalanced pumping system may be pivotally mounted on a tower thus allowing for installation of pump seals above ground.

Abstract: An improved pump jack assembly for reciprocating a sucker rod in a well bore is disclosed. The pump jack assembly includes a walking beam pivotally mounted for free swinging motion on a Sampson post. The walking beam includes a fixed counterweight mounted on one end and a horsehead mounted on the opposite end. The walking beam is driven in up-and-down pumping motion by a pair of balance weights which are coupled for coordinated reciprocal movement along the walking beam. The balance weights are linked together for concurrent movement and are driven by a hydraulic cylinder mounted on the counterweight end of the walking beam. The weights are so positioned that while one weight is being raised by the hydraulic cylinder, the other weight is falling due to gravity. Thus the weights help each other and greatly reduce the power requirement. The downward stroke of each end of the walking beam is limited by saddle weights which are pivotally coupled to the walking beam on opposite sides of the Sampson post. A pedestal disposed in the path of movement of each saddle weight engages the saddle weight and limits its downward movement as the walking beam nears the limit of its downward stroke.

Abstract: An inertia bar to be installed in a well between a sucker rod string and a subsurface pump. A string of the bars adds weight to the sucker rod string and maintains it under tension throughout a pumping cycle. A sufficient number of the bars are used to place a neutral zone within the inertia bars. The neutral zone is a zone in which there is neither tension nor compression in the bars. The body of each bar has a relatively large diameter, which for example may be the same as the outside diameter of the couplings used to connect the individual sucker rods. The bar has pins at its ends for engaging the couplings, which pins have the same dimension as standard sucker rod pins. The bar can be engaged by a conventional elevator when it is to be removed from a well.
