Shock absorbers that only resist motion in one direction?

  1. May 16, 2005 #1
    I was just wondering if there are shock absorbers on the market that will allow motion in one direction freely, but resist motion in the opposite direction; thanks.

    You mean like the one on a screen door?

    Don't forget to remove the spring. I used a screen door closer as a slow-closer on my kids' toybox. With the spring inside, it closed slowly... after first slamming shut like a steel trap! Removing the spring made it work like I wanted it to. Opens easily, closes slowly.

    Thanks... do you know if there's a technical name for these things? I need to buy a couple for a project I'm doing for school.

    Unless you're looking for a specific brand, they're just called 'screen door closers'. Make sure you have the 'screen' type as opposed to a regular closer made for heavier doors. They're a lot cheaper and don't have all of the unnecessary adjustments like back-check and initial and final speed settings. Also, they're easier to mount and are linear rather than rotary in action.
