Abstract
A pump attenuator bypass valve (40/100/200) is located at an outlet of a pump (30) in a vehicle braking system (10) between the pump (30) and an attenuator (34). The attenuator bypass valve (40/100/200) includes a bypass valve housing (41), a first fluid flow path (74, 57/179/220, 208), and a second fluid flow path (80/183). The first fluid flow path (74, 57/179/220, 208) is defined in the housing (41) and is configured to allow continuous flow of fluid when the pump (30) operates at a first pump flow rate. The second fluid flow path (80/183) is defined in the housing (41) and is configured to bypass the first fluid flow path (74, 57/179/220, 208) and to allow continuous flow of fluid when the pump (30) operates at a second pump flow rate higher than the first pump flow rate.
