摘要： In a control system for a vehicle having a transmission with fluid actuated frictional engaging means and brake means wherein a first hydraulic passage means interconnects a fluid pressure source with the frictional engaging means, a regulating valve is disposed in the first hydraulic passage means, for regulating the pressure of the pressure fluid supplied to the frictional engaging means, with the regulating valve means also being operatively connected with the brake means and responsive to the degree of actuation of the brake means and actuatable between a first and a second position, whereby in the first position the pressure fluid can freely flow into, through and out of the inching valve toward the frictional engaging means, however in the second position, the fluid flow through a first set of radial apertures is blocked by a regulating spool and thereafter further radial apertures are progressively opened by the regulating spool means so as to regulate the force of the pressure fluid acting on the frictional engaging means. One embodiment of this invention is a downstream regulator that regulates the flow of pressure fluid into the regulator valve whereas another embodiment of this invention is a bypass type downstream regulator valve that regulates the flow of pressure fluid out of the regulator valve. Both of these embodiments feature a quick initial pressure drop over a short distance of valve travel, followed by a low further pressure drop over a long distance of valve travel, thus permitting insensitive control by the vehicle operator and thereby permitting smooth vehicle performance.

摘要： A transmission control apparatus for a vehicle having a transmission with fluid actuated clutch means and hydraulic brake means wherein a first fluid conduit, having a fluid flow constricting means interposed therein, connects a fluid pressure source with the clutch means, with an inching valve means being fluidically connected in parallel with the first conduit by second and third conduits upstream and downstream respectively, from the fluid flow constricting means, for regulating the pressure of the pressure fluid supplied to the clutch means, with the inching valve means also being operatively connected with the brake means and responsive to the degree of actuation of the brake means and actuatable between a first and a second position, whereby in the first position, the pressure fluid can freely flow into, through and out of the inching valve toward the clutch means so as to effectively bypass the fluid flow constricting means, however in the second position, the fluid flow through the second conduit is blocked off and the flow of fluid toward the clutch means is forced to flow solely through the fluid flow constricting means, thereby keeping the clutch means filled with fluid at all times. A further conduit connects the pressure fluid with the clutch means for lubrication and cooling purposes, with the fluid flow constricting means, in the second position, functioning to lower the fluid flow through the first conduit so as to increase the amount of fluid flow into the further fluid conduit.
