摘要： Hydraulic systems and tools having an actuator that actuates a pump and a control valve are described. The pump transports fluid into a chamber to advance a piston in the chamber. The control valve is biased open and regulates flow of hydraulic fluid from the chamber to a reservoir. The actuator is operable in a first state in which the control valve is open, allowing flow of fluid from the chamber to the reservoir, and the pump is not pumping. The actuator can be operated in a second state in which the control valve is closed, restricting flow of fluid from the chamber to the reservoir, and the pump is not pumping. The actuator can be operated in a third state in which the control valve is closed and the pump is pumping fluid from the reservoir into the chamber in order to advance the piston.

摘要： A basin wrench is described having a telescoping assembly, pivotal jaws, a light, and a removable T-bar assembly. The wrench includes a polymeric housing having a contoured gripping region. The T-bar assembly includes a pivotally mounted hub and bar slidably retained within the hub. The T-bar assembly can be placed in a stowed position in which the bar is positioned alongside the housing. The wrench also includes magnetic retaining provisions to retain the T-bar assembly in its stowed position.
