Valve assembly and anti-lock braking system including the same

A valve assembly for use in an electric and/or hydraulic anti-lock braking system for a vehicle, the valve assembly including:

• a valve body comprising a valve chamber, a first fluid port, a second fluid port, and a third fluid port, wherein the first fluid port, the second fluid port and the third fluid port are in fluid communication with the valve chamber;
• a first plunger movably disposed within the valve chamber and configured to be moved between an open position and a closed position, wherein when the first plunger is in the open position the first fluid port is in fluid communication with the second fluid port, and wherein when the first plunger is in the closed position the first fluid port is fluidly isolated from the second fluid port;
• and
• a second plunger movably disposed within the valve chamber and configured to be moved between an open position and a closed position, wherein when the second plunger is in the open position the second fluid port is in fluid communication with the third fluid port, and wherein when the second plunger is in the closed position the second fluid port is fluidly isolated from the third fluid port,
• wherein the first plunger is configured to be moved from the closed position to the open position by moving the first plunger in a first direction, and the second plunger is configured to be moved from the closed position to the open position by moving the second plunger toward the first plunger in a second direction opposite the first direction,
• wherein the second fluid port is arranged on the same side as the first fluid port and the third fluid port with respect to the first and second plungers,
• wherein the first plunger and the second plunger overlap each other in a direction perpendicular to the first and second directions, the first plunger being disposed outside the second plunger in the direction perpendicular to the first and second directions, and
• wherein when the first plunger is in the open position the first fluid port is in fluid communication with the second fluid port by way of a first fluid connection, wherein the first plunger is continuously movable and wherein the first plunger and the first fluid connection are configured such that a minimum cross section of the first fluid connection is continuously variable by moving the first plunger.
