Title:
HYDRAULIC HAND TOOL
Document Type and Number:
WIPO Patent Application WO2005081620
Kind Code:
B1
Abstract:
A handheld hydraulic assembly tool (10,210) for advancing a fitting's swage ring (SR) onto a fitting's connecting body (CB) while a conduit (C) is received in the connector body (CB) to mechanically and sealingly connect the fitting (F) to the conduit (C) includes a clamping assembly (22,222) defining a piston chamber (38,238) fluidly connected to a pump chamber (94,334). The clamping assembly (22,222) has a fixed jaw (30,230) adapted to engage one of the connector body (CB) and the swage ring (SR) and a moveable jaw (34,234) adapted to engage the other of the connector body (CB) and the swage ring (SR). A piston (28,228) is disposed in the piston chamber (38,238). The piston (28,228) and the moveable jaw (34,234) are configured such that movement of the piston (28,228) in a first direction moves the moveable jaw (34,234) toward the fixed jaw (30,230) thereby moving the swage ring (SR) axially onto the connector body (CB) to mechanically and sealingly connect the connector body (CB) to the conduit (C) received therein when the jaws (30,34,230,234) are engaged to the connector body (CB) and the swage ring (SR). A pump body (16,216) defines the pump chamber (94,334) and is connected to the clamping assembly (22,222). A fluid reservoir (14,214) is fluidly connected to the pump chamber (94,334). A manually-operated pump piston (92,332) is disposed in the pump chamber (94,334) for drawing hydraulic fluid from the fluid reservoir (114,214) and forcing the drawn hydraulic fluid into the piston chamber (38,238) to move the piston (28,228) in the first direction.
