5. Hydraulic tappet - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_tappet

   A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. This clearance prevents the parts ...

   en.wikipedia.org/wiki/Hydraulic_machinery

   The hydraulic fluid reservoir holds excess hydraulic fluid to accommodate volume changes from: cylinder extension and contraction, temperature driven expansion and contraction, and leaks. The reservoir is also designed to aid in separation of air from the fluid and also work as a heat accumulator to cover losses in the system when peak power is ...

9. Telescopic cylinder - Wikipedia

   en.wikipedia.org/wiki/Telescopic_cylinder

   Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi. This is because the outward forces produced by internal hydraulic pressure tends to expand the steel sleeve sections. Too much pressure will cause the nested sleeves to balloon outward, bind the mechanism and stop moving.
