True or False? During pump operation, the

pressurization phase increases the volume in the

pumping chamber.

The maximum pressure developed in the system

is determined by the resistance to the flow of fluid

in the system and the force that can be applied to

the

All pumps used in hydraulic systems can be

classified according to

A$.$ displacement

B$.$ pumping motion

C$.$ fluid delivery characteristics

D$.$ All of the above.

Pump produces a constant output for

each revolution of operation over a wide range of

operating pressures.

A$.$ positive$-$displacement

B$.$ nonpositive$-$displacement

C$.$ rotary

D$.$ All of the above.

The pump that includes a mechanism allowing

an operator to easily vary the size of the pumping

chamber is classified as a$(n,$ delivery

design.

A$.$ variable

B$.$ external

C$.$ internal

D$.$ fixed

The most popular hydraulic pump uses

gears as the primary elements of the pumping

mechanism.

A$.$ external

B$.$ internal

C$.$ variable

D$.$ inline

Two variations of this design are commonly

found in hydraulic systems:

and crescent

designs.

The vane pump design achieves a pumping

action by placing the slotted rotor and vanes in an

offset position in the pumping chamber.

A$.$ crescent

B$.$ unbalanced

C$.$ sliding

D$.$ balanced
