Abstract
The present disclosure relates to a valve arrangement for use with a steering assist system having left and right brake actuating members. The valve arrangement includes a valve body defining a left brake port adapted for connection to a left hydraulic brake and a right brake port adapted for connection to a right hydraulic brake. The valve arrangement also includes a left valve member for controlling hydraulic fluid flow through the left brake port, and a right brake valve member for controlling hydraulic fluid flow through the right brake port. The left brake valve member is adapted to be actuated by the left brake actuating member, and the right brake valve member is adapted to be actuated by the right brake actuating member. The valve arrangement also includes structure for providing equal hydraulic braking pressures to the left and right brakes through the left and right brake ports when the left and right brake actuating members have been actuated on equal amounts.
