oil pulse tool

HST-EYP / HST-EYPS

Oil pulse tools for industrial applications

  • 5 - 600 Nm
  • High torque repeatability
  • Less maintenance
    Pulse unit consists of significant less parts as tools of other manufacturers
  • Lower oil warming
    Thereby a significant higher oil replacement (without vacuum pump system)
  • Simple torque adjustment
  • Less reaction force to the operator´s wrist, arm and shoulder
  • Pricewise an interesting alternative


Features

  1. Durable oil seal
    Sealing lower pressure oil

  2. Simple Structure
    Presents maximum torque output
    - patented -

  3. Protector
    For the protection of the work piece

  4. Direct air shut-off
    New mechanism
    - patented -

  5. Changeable driving end
    Multiple driving ends available
    - patented -

  6. Relief valve

  7. Ergonomical handle
    For a better handling of the tool




Torque shut-off precision also while supply air fluctuates


The unique design of HST-EYP pulse tools, combining pulse unit and air shut-off mechanism, provides the most excellent accuracy of shut-off torque while supply air pressure fluctuates between 4 bar and 6 bar or more.


While generating a pulse, some amount of high pressure oil is going through the internal oil passage (tunnel) in the wall of the anvil and flows into the oil chamber through the check valve orifice. During a series of pulses, the accumulated volume of oil in the chamber keeps increasing and finally activates the shut-off piston.

When the supplied air pressure goes down, the rotation of the air motor slows down and simultaneously, the number of pulses being generated becomes lower, also. As a result it takes more time to build up enough fluid pressure to activate the shut-off piston which will transmid fluid force to the air shut-off valve by way of the signal pin located in the center of the rotor.


This automatic self-controlled mechanism is called „DIRECT AIR SHUT-OFF“, and it is patented.

Illustration on the top shows how stable shut-off torque can be maintained even if the supplied air pressure fluctuates between 4 bar and 6 bar.
