travel s and effective travel s′

A limit switch (162) is used to terminate the end of the retracting stroke.

The travel loss of so shall not exceed 10 per cent of the effective travel s′.

The travel loss of so shall not exceed 10 per cent of the effective travel s′.

Check of control travel

In a stroke sensor abnormality determining device, a stroke sensor (46) detects the stroke of a brake pedal (12) by detecting a voltage that varies in accordance with the stroke of the brake pedal (12).

Also, the control device (20) controls the stroke state of the suspension on the basis of the stroke speed (Vz) (stroke speed estimated value (VzSH)) after removal of said component.

The device includes a means responsive to the flexure of the element in the ejection stroke to terminate that stroke and begin the filling stroke.

maximal stroke position displacement

Conversely, the outlet valve is adapted to open the outlet during the expulsion stroke, and to close the outlet during the uptake stroke.

The inlet valve is adapted to open the inlet during the uptake stroke, and to close the inlet during the expulsion stroke.

Check of control device travel

To compensate stroke generator drift, a modified actual stroke signal which makes allowance for the deviation of the measured maximum stroke from the design value of the maximum stroke of the pump piston (14) is used for the comparison.

The roller bearing may generally facilitate the movement of the top race relative to the bottom race while subject to a substantial load on the top race.

According to the invention, the machine tool is automatically switched from rapid travel to working travel when a defined counter-force occurs.
