油圧ハンドツール
Document Type and Number:
Japanese Patent JP2007526831
Kind Code:
A
Abstract:
A handheld hydraulic assembly tool for advancing a fitting's swage ring onto a fitting's connecting body while a conduit is received in the connector body to mechanically and sealingly connect the fitting to the conduit includes a clamping assembly defining a piston chamber fluidly connected to a pump chamber. The clamping assembly has a fixed jaw adapted to engage one of the connector body and the swage ring and a moveable jaw adapted to engage the other of the connector body and the swage ring. A piston is disposed in the piston chamber. The piston and the moveable jaw are configured such that movement of the piston in a first direction moves the moveable jaw toward the fixed jaw thereby moving the swage ring axially onto the connector body to mechanically and sealingly connect the connector body to the conduit received therein when the jaws are engaged to the connector body and the swage ring. A pump body defines the pump chamber and is connected to the clamping assembly. A fluid reservoir is fluidly connected to the pump chamber. A manually-operated pump piston is disposed in the pump chamber for drawing hydraulic fluid from the fluid reservoir and forcing the drawn hydraulic fluid into the piston chamber to move the piston in the first direction.
