    Abstract: An automatic vehicle brake control system is disclosed which actuates a vehicle brake system in response to a transmission shift by a vehicle operator, as between a forward and reverse vehicle direction. The control system automatically provides for engaging the vehicle brakes upon the initiation of the transmission shift by the operator. The vehicle brakes are not released until a safe shifting speed is reached by the vehicle to allow the actual vehicle transmission shift to be accomplished safely. Structurally, the control system has an anti-plug valve connected to a manually operated transmission control valve and to a brake system control valve. The switching of the transmission control valve actuates the anti-plug valve which provides an adjustable time delay between actuation of the actual vehicle transmission shift corresponding to the shift indicated by the transmission control valve. During this time delay, the anti-plug valve causes the vehicle brakes to be actuated to slow down or stop the vehicle thereby preventing inertial shock to the vehicle transmission.

    Abstract translation: 公开了一种自动车辆制动控制系统，其响应于车辆操作者在正向和反向车辆方向之间的变速器换档而致动车辆制动系统。 控制系统自动地提供在操作员开始变速器换档时接合车辆制动器。 车辆制动器在车辆达到安全的换档速度之前不会释放，从而可以安全地实现实际的车辆变速箱换档。 在结构上，控制系统具有连接到手动变速器控制阀和制动系统控制阀的防旋塞阀。 变速器控制阀的切换致动止动阀，其提供对应于由变速器控制阀指示的档位的实际车辆变速器变速的致动之间的可调节的时间延迟。 在该时间延迟期间，防插塞阀使得车辆制动器被致动以减慢或停止车辆，从而防止对车辆传动装置的惯性冲击。

    Abstract: A hydraulic switching mechanism is formed of two cooperating valves, the first being a rotary type which directs fluid under pressure to a second valve of the sliding spool type which has springs at both ends to hold the spool in the neutral position. The rotary-type is formed of a body having a pair of diverging passages connecting through a chamber with an inlet port; a rotary valve member, having a passage therethrough connecting with the inlet port, is located in the chamber and is actuated by a reversible shaft to select the movement of fluid through the valve member into one or other of the diverging passages, these in turn being connected to a respective end of the spool valve thereby moving the spool out of neutral against a respective spring. The spool has a pair of ports which are connected to individual clutches, the actuation of which depends on the selected direction of flow in the switching mechanism.
