Abstract

PURPOSE: To prevent loss of pressure in a reservoir even if one system is damaged by installing a differential shut off valve between a relay valve and brake chambers in order to provide two systems.
CONSTITUTION: Brake lines from a tractor is introduced to a relay valve 1 with an emergency valve via connectors 11 and 24, and a reservoir 44 is connected to the relay valve 1. The pipe from an outlet B of the relay valve 1 is divided into two, which are respectively led to brake chambers 63 and 70 via a differential shut off valve 50. Since a chamber 55 or 56 of one damaged system in the differential shut off valve 50 is kept at an atmospheric pressure by the works of small holes 57 and 64, a differential piston 53 is shifted by the pressure difference from a chamber of another system. Since a valve 74 or 76 in the damaged system is closed by the shift of the differential piston 53, the air is prevented from further escape.
