Title: Improvements in or relating to distributor valve apparatus for pneumatic braking installations of combination vehicles
IPC: B60T15/04
Filed: 1960-03-17
Abstract: 930,442. Fluid-pressure brakes. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. March 17, 1960 [March 26, 1959], No. 9548/60. Class 103 (1). A distributer valve apparatus for pneumatic braking installations of tractor-trailer vehicles comprises three distributer valves D1, D2, D3 adapted to be actuated by operation of a vehicle brake pedal, one (D3) by a slide 44 having an associated push rod 46 adapted to be coupled to the vehicle brake pedal and the other two (D1, D2) by means of a balancing element 40 movement of which is effected by movement of the slide 44, the distributer valve D3 being also adapted to be independently actuatable from a manual control device by means of a further push rod 70 slidably mounted with respect to the slide 44 and coupled to the manual control device so as to be moved relatively to the slide 44 to actuate the distributer valve D3 when such device is operated. The Figure shows the apparatus in an inoperative position and during normal braking, the driver by acting on the brake pedal displaces the push rod 46 and moves slide 44 which, by means of the balancing element, actuates the distributer valves D1 and D2 leading to the individual braking sections of the tractor vehicle and also distributer valve D3 leading to the braking section of the trailer vehicle by means of the extension 90 and flange 92. During the first part of the movement of the slide 44 before the distributer valves operate, the slide 44 actuates a tractor vehicle exhaust brake switch I 1  which provides a braking action preceding that given to the distributer valves. Also at the first movement of the slide 44, a stop switch I 2  is actuated since the rod 70 causes rotation of lever 52 causing movement of appendix 65 which operates switch I 2 . If desired the actuation of distributer valves D1, D2 and D3 can be arranged to be non-simultaneous so that the trailer vehicle distributer valve D3 may be given a certain priority over the tractor vehicle braking sections D1, D2.
