IPC: B60T8/46
Filed: 1985-12-10
Abstract: PURPOSE:To make pressurization ratio of brake oil pressure variable by means of restriction effect by forming a pressorizing solenoid valve device fitted in a path from an accumulator up to a brake device, in a switching mode for flow restriction state and in another switching made for flow path full-open state. CONSTITUTION:A pressuring valve 20 is fitted into a main path 4 on the lower stream from a gate valve 1 on a path of a brake oil pressure pressurizing system extending from an accumulator 12 up to a brake device. Now, said pressure valve 20 is enabled to be switched between a normally-open mode (a) and a restriction mode (b) of flow path in order to be maintained at the normally-open mode (a) in normal condition, and to switch to the restriction mode (b) in the case of requiring pressure reduction of anti-skid control and gentle pressurization. And, said switching control is operated by an electronic controller depending on the behavior of the rotary movement of a wheel. Therefore, pressurizing ratio of brake oil pressure for anti-skid can be changed by restriction effect, and no switching by high frequency of a solenoid valve is employed. Consequently, durability can be improved.

Thus the difference signals showing the difference of received light quantity between the photodetectors 9 and 10 as well as between the photodetectors 11 and 12 are defined as the focus error signals respectively. That is, the difference signal never exists at a focused position since the beams 15 and 16 are focused on the dividing line between photodetectors 21 and 22.
