Title: Negative pressure equipment for automobile
Inventor: UDONO JIYUN
IPC: B60T17/04
Filed: 1980-06-20
Abstract: PURPOSE:To protect the braking function by making full play as the orifice at the time of having deficiency on the actuator by providing an orifice on a check valve to another negative pressure actuator using negative pressure source of a negative pressure brake booster. CONSTITUTION:A check valve 31 which communicates the negative pressure source 21 to a negative pressure actuator 27 has its valve body 36. Since operation of the actuator 27 at the normal time does not enlarge pressure difference on the right and left sides of the valve body 36, the left end 36 of the valve body 36 does not close its valve port 35. In consequence, the valve 31 fulfills the same function as the conventional check valve. When the actuator 27 has deficiency, pressure difference on the right and left sides of the valve body 36 enlarges, and the left end 36b of the valve body 36b closes the valve body 35. Thus, even if a large quantity of air flows into a chamber 32, an orifice 38 prevents flowing to the negative pressure source side, and prevents a negative pressure booster 22 from losing its function.
