Abstract
An economical, light and reliable hydraulic braking system for braking a moving mass includes a pressure element or press part for pressing onto a brake surface under frictional contact, a brake actuator filled with hydraulic fluid for producing pressure in the pressure element and a spacing device for adjusting play between the pressure element and the brake surface when the brake system is in a released or non-active position. The spacing device includes a hydraulic accumulator for accumulating a predefined volume of hydraulic fluid at a minimum pressure. The hydraulic accumulator can be connected to the brake actuator, thus avoiding the use of mechanical stopping or blocking devices.

A hydraulic braking system for braking a moving mass, the hydraulic braking system comprising:
- a pressure element for pressing against a brake surface with frictional contact;
- a brake actuator filled with hydraulic fluid for generating a pressure to be introduced into said pressure element;
- and
- a spacing device for adjusting play between said pressure element and said brake surface when the braking system is in a released position;
- said spacing device having a hydraulic accumulator for accumulating a predefined volume of hydraulic fluid at a minimum pressure;
- and
- said hydraulic accumulator configured to be connected to said brake actuator to avoid using mechanical stopping or blocking devices.
A method for adjusting play between a pressure element of a hydraulic brake and a brake surface, the method comprising the following steps:
- applying a predefined pressure to a predefined volume of a hydraulic fluid, to move the pressure element and lift the pressure element from the brake surface;
- and
- using only the volume of the hydraulic fluid to delimit the movement of the pressure element and determine a distance between the pressure element and the brake surface in a released position of the brake.
