  • Patent number: 4041809
    Abstract: The transmission arrangement includes first and second hydraulically activatable units. When the first and second units are activated and unactivated, respectively, the arrangement exhibits a first transmission ratio. When the first and second units are unactivated and activated, respectively, the arrangement exhibits a second transmission ratio. Electrically controllable first and second valves each connect an associated unit to a source of hydraulic fluid. A transmission-ratio changeover is effected by causing the valves to undergo opposite changes of energization state. Each valve has its own time-delay stage. Upon receipt of a signal commanding a transmission-ratio changeover, each time-delay stage delays the initiation of the change of energization state of the associated valve by a respective time-delay interval.
