What type of directional control
valve is normally used to control
a single-acting, spring-loaded,
piston-type actuating cylinder?
1.
Shuttle
2.
Transfer
3.
Three-way
4.
Four-way
Refer to figure 10-6 of your
textbook.
This type of cylinder
is normally installed so that the
greater load is carried as the
piston travels in which
direction?
1.
To the right
2.
To the left
3.
To either the right or left:
it does not matter since the
same pressure is applied to
both sides of the piston
Refer to figures 10-6 and 10-8 in
your textbook.

unbalanced cylinder differs from
a double-acting balanced cylinder
in that the balanced cylinder has
1.
equal,
opposing piston
surfaces
2.
unequal piston rod areas
3.
unequal piston surface areas
4.
springs to equalize pressures
on the piston
