Before torque

generation

There is no pressure

difference, and only

the liner casing and

liner rotate.

Torque generation

The torque-generating seal portion of

the main shaft matches that of the liner.

Four chambers of different pressure are

formed. High pressure works on the

blade and causes the main shaft to

rotate. This action generates torque.

After torque

generation

There is no pressure

difference, and only the

liner casing and liner

rotate.

Motor rotation

The torque-generating seal portion of

the main shaft does not match that of

the liner (see 3 ).

There is no pressure difference, and

only the liner casing and liner rotate.

• Impact mechanism of oil pulse driver

Quiet: 75 dB

While the impact mechanism of a conventional impact driver generates impact force by striking iron pieces

for impact driving, an oil pulse driver generates high impact force by applying motor rotational force to an oil

pulse section (in an oil pressure mechanism), thereby increasing oil pressure in the section and using this

force for tightening screws. The oil pulse driver is much quieter than the impact driver since it does not

strike iron pieces to generate force.

As shown in operations 1 , 2 , 3 , and 4 above, this mechanism generates one torque per revolution of

the main shaft (one impact per revolution).
