Pressure-actuated clutch and brake

A press comprising:

• a nonrotating tube shaft centered on an axis;
• a rotatable output shaft coaxially received in the tube shaft and having a shaft end;
• a supply of fluid under pressure;
• a brake element fixed on the tube shaft;
• an axially movable brake element angularly coupled with the output shaft and forming with the fixed brake element a pressurizable brake chamber;
• brake-actuating means including a fluid line extending from the brake chamber through the tube shaft to the fluid supply for pressurizing the brake chamber and thereby coupling the brake elements with each other, whereby the output shaft is braked against the tube shaft;
• a flywheel rotatable about the axis on the tube shaft;
• a first clutch element rotatable about the axis and angularly coupled to the flywheel;
• a second clutch element rotatable about the axis adjacent the first clutch element and forming therewith a pressurizable clutch chamber;
• and
• clutch-actuating means including another fluid line extending from the clutch chamber to the fluid supply for pressurizing the clutch chamber and thereby coupling the clutch elements with each other, whereby the output shaft is coupled to the flywheel.
