Inside parallel plane surface in order to control the fluid pressure inside the ABS brake gear of the vehicle, or the pressure control valve device which has the diaphragm valve which has the diaphragm which is arranged in same plane

摘要

As for this invention, fluid pressure inside ABS brake gear of vehicle, individual wheel of vehicle (3a and 3b; As 4a and 4b) while to the tendency which locks being, brake pressure inside the brake cylinder (6a - 6d) which corresponds been adaptation adjustment possible, being the pressure control valve device (7) in order to control, inside the housing (18) of the said pressure control valve device (7), with the control control equipment (10) of electronic type in order the diaphragm valve (14a and 14b) and the said diaphragm valve (14a and 14b) which at least have two which is loaded by the spring component (16a and 16b) diaphragms (20a and 20b) the pilot to control controlPossibility it regards those of the type where the control valve (15a and 15b) of one electromagnetic type is provided at least. With this invention, inside one aspect (25) of the housing part (17) of the aforementioned housing (18), it loads or to insert, or opening (19a and 19b) in order has been provided the aforementioned diaphragm (20a and 20b), the edge (22a and 22b) of the aforementioned diaphragm (20a and 20b), the opening edge (23a and 23b) of the aforementioned opening (19a and 19b) and, to be kept with another housing parts (24) of the aforementioned housing (18), the aforementioned opening edge of the aforementioned opening (19a and 19b) (23a23b) inside one common plane surface, or has been located inside parallel plane surface, at the same time surface normal line (44) of the aforementioned opening edge (23a and 23b) of the aforementioned opening (19a and 19b) tried the same direction to be faced.
