Abstract
A hydraulic tool includes a handle having a trigger, a tool head, a tool body, a pump, a first actuator, a second actuator, and a conduit. The tool head has a first jaw and a second jaw. The tool body includes a first portion, an extension, and a second portion positioned between the handle and the tool head. The pump is activated by the trigger to displace a first fluid. The first actuator is moveable by the displacement of the first fluid to displace a second fluid. The second actuator is moveable by the displacement of the second fluid to cause movement of at least one of the first and second jaws. A conduit provides fluid communication between the first actuator and the second actuator.
Claims18
A hydraulic tool comprising:
- a handle having a trigger;
- a tool head for performing an operation;
- a pump activated by the trigger to displace a first fluid;
- a first actuator moveable by the displacement of the first fluid to displace a second fluid;
- and
- a second actuator moveable by the displacement of the second fluid and operatively connected to the tool head,
- wherein the first fluid is isolated from the second fluid.
A tool comprising:
- a handle having a trigger;
- a first actuator operatively connected to the trigger
- a tool head;
- an extension positioned between the handle and the tool head;
- and
- a second actuator operatively connected to the first actuator and to the tool head,
- wherein the extension is made from a non-conductive material and includes a hollow portion filled with a foam material.
