<p>The valve (actuating mechanism) (100) is used for supplying pressure, decompression and pressure maintenance. It drives multiple piston distributors (30, 32, 34) which travel up and down in a housing (20) in passage holes (22, 24) by making use of elements of alloys having memory for a linear form (40, 42, 44). The anti-blocking brake system (200) uses valve (100) in which the respective passage holes (22, 24) have intake (22, 24a) and discharge (22b, 24b) holes. The system includes a mechanism (60) for retaining the piston distributors (30, 32, 34) in lower position which is mounted in the lower sector (28) of housing (20) and the piston distributors (30, 32, 34) are returned to their original positions for shifting springs. A main cylinder (22) , wheel brake and hydraulic pump (242) are connected to the intake (22a, 24a) and the discharge (22b, 24b) holes of valve (10) . An electronic control unit (70) is connected to the elements of alloys with momory for form (40, 42, 44) in order to actuate them and in this way pressure, decompression and pressure maintenance of the wheel brake are supplied.</p> |
