Relay valve control arrangement to provide variable response timing on full applications

摘要: A brake system and related components including a metering device are configured to regulate control signal received from such that valve delays the supply of level requested braking pressure for prescribed amount time. The can be an inversion orificed check in circuit adapted allow relatively unrestricted flow until threshold is reached, after which closes metered through orifice. This has effect allowing rapid actuation first level, then slowing further application full achieved. An electronic unit also delay development pressure.
