Vented valve and brake system using same

A venting valve, comprising:

• an elongate venting valve bore having longitudinally spaced first and second bore ends, with a bore lumen extending between the first and second bore ends, the venting valve bore being at least partially defined by a venting valve body;
• an MC valve passage in fluid communication with the bore lumen adjacent the first bore end, the MC valve passage being configured to selectively place the bore lumen in fluid communication with a master cylinder selectively transmitting pressurized hydraulic fluid through the venting valve;
• a venting fluid passage in fluid communication with the bore lumen at a location spaced longitudinally from the MC valve passage;
• an SCA valve passage in fluid communication with the bore lumen at a location longitudinally interposed between the MC valve passage and the venting fluid passage, the SCA valve passage being configured to selectively place the bore lumen in fluid communication with a single corner actuator selectively transmitting pressurized hydraulic fluid through the venting valve along a valve fluid path extending through a portion of the bore lumen and linking the MC valve passage and the SCA valve passage;
• an elongate venting valve shuttle extending partially through the bore lumen for selective longitudinal reciprocal motion at least partially between the first and second bore ends between first and second shuttle positions at least partially responsive to fluid pressure along the valve fluid path, the venting valve shuttle having longitudinally spaced first and second shuttle ends, with the second shuttle end selectively located longitudinally adjacent the second bore end;
• and
• a valve ball located in the valve bore and interposed longitudinally between the venting valve shuttle and the first bore end, the valve ball being selectively engaged with a valve seat defined by the valve bore to selectively occlude the valve fluid path responsive to a predetermined fluid pressure at the SCA valve passage and to maintain the valve fluid path responsive to at least one of the predetermined fluid pressure at the SCA valve passage and a predetermined fluid pressure at the MC valve passage;
• wherein the venting valve shuttle shifts longitudinally toward the second shuttle position responsive to presence of a predetermined hydraulic pressure level within the bore lumen along the venting valve fluid path, shifting of the venting valve shuttle toward the second shuttle position being operative to urge air from the bore lumen into the ambient space via the venting fluid passage;
• wherein the valve ball engages with the valve seat at least partially responsive to shifting of the venting valve shuttle toward the second shuttle position;
• and
• wherein shifting of the venting valve shuttle toward the first shuttle position is operative to urge air into the bore lumen from the ambient space via the venting fluid passage.
