  • Publication number: 20080079221
    Abstract: A seal valve arrangement is provided for a hydraulic device (10). The hydraulic device has an inner bore (14). The seal valve arrangement includes an element (45) disposed in the bore. The element is constructed and arranged to define a fluid passage (47) so fluid can move from one side thereof to a side opposite the one side. An elastomer seal member (39) is adjacent to the fluid passage and to a seal portion (r) of the element. A spring member (41) biases the seal member to engage the portion (r) to maintain sealing of the fluid passage under certain fluid pressure conditions, and under different fluid pressure conditions, permits the seal member disengage from the portion of the element to open the fluid passage. A tipping point is disclosed as a point when a fluid pressure condition alone causes the seal member (39) to fully engage the portion of the element and fully seal the fluid passage.

  • Publication number: 20070089558
    Abstract: A force multiplying structure includes a central cam 132 associated with an output shaft 28. A first link structure 114 has one end pivotally coupled to a first member 112 of a tool and another end is pivotally coupled to the central cam 132. A first roller 30? is associated with the first link structure 114 and rotates on the cam surface 130 of the first member 112 and on a surface of the central cam 132. A second link structure 118 has one end pivotally coupled to a second member 122 of a tool and another end is pivotally coupled to the central cam 132. A second roller 30? is associated with the second link structure and rotates on the cam surface 138 of the second member and on a surface of the central cam 132. Movement of the output shaft causes the first and second link structures to move, causing the first member 112 to move and engage the object with a force increased from a force exerted by the output shaft. The rollers carry loads exerted on the first and second link structures.

  • Publication number: 20060230810
    Abstract: A hydraulic operated tool includes a body B, a pair of jaws 21 mounted with respect to the body so that at least one of the jaws is movable between an opened jaw position and a closed jaw position so as to engage workpiece W between the jaws. A ram assembly 2 is disposed in the body and is operatively associated with the jaws. Spring structure 1 causes the ram assembly to move thereby causing the jaws to initially engage the workpiece with a first force. A pump assembly 7 exerts fluid on the ram assembly to move the ram assembly further, causing the jaws to exert a second force, greater than the first force, on the workpiece.
