Question #82

The component that converts hydraulic oil pressure into mechanical movement is:

Elementem przekształcającym ciśnienie oleju hydraulicznego w ruch mechaniczny jest:

a
a piston pump

pompa tłoczkowa

b
a hydraulic cylinder

siłownik hydrauliczny

Correct answer

c
a hydraulic directional control valve

rozdzielacz hydrauliczny

d
a pressure relief valve

zawór przelewowy

Why?

Pressurised oil acts on the piston in the hydraulic cylinder (siłownik hydrauliczny), producing movement such as lifting the forks. The pump supplies oil and the directional control valve (rozdzielacz hydrauliczny) directs its flow, but neither replaces the cylinder that produces the movement.
