Hydraulic operating system for roller skate and rollerblade brakes

摘要

The hydraulic operating system (1) is for brakes with an anti-flattening or anti-blocking function, such as for roller skates or rollerblades. It has at least one active section (2,3), and an enclosed compression/expansion vol. in a one-piece structure. It is in a material with a hardness and a geometry to direct the compression/expansion actions to the active sections (2,3). The active sections (2,3) have a connection to a channel (4). A chamber with a hydraulic medium is structured with at least one end wall which has an axial movement on a change in the hydraulic pressure. The operating system (1) is of an injection molded elastic elastomer, thermoplastic or heat-setting plastics material, with a hardness of 65-75 deg Shore (A).
