ABSTRACT:
This invention relates to a brake valve device having a fluid pressure operated relay valve device for varying the pressure in a train brake pipe in accordance with the degree of fluid under pressure supplied to an equalizing reservoir and the relay valve device by a control valve device wherein the control valve device is operative, in a release position of a brake valve handle, in the manner of a self-lapping valve device to establish a preselected pressure of the fluid supplied to the equalizing reservoir and the relay valve device, and, in a service and lap position of the brake valve handle, in the manner of a manually-operated brake valve device, to release fluid under pressure from the equalizing reservoir and relay valve device to atmosphere. Therefore, the time that the handle remains in the service position determines the degree of reduction of the pressure of the fluid in the equalizing reservoir and the relay valve device. Upon manual return of the handle to its release position, the control valve device operates in the manner of a self-lapping control valve device to effect charging of the equalizing reservoir to a preselected pressure which operates the relay valve device to effect charging of the train brake pipe to this preselected pressure.
