FIELD: automotive industry.
SUBSTANCE: invention relates to automotive industry, particularly to transmission. To reduce work pressure, proposed design prevent abrasive wear of check valve. The latter (70), arranged in oil feed channel running from mechanical pump, seats between valve bodies (40) due to attachment of valve box (72) gearbox case (41). Note here that axial direction of said valves complies with direction of gravity force. Oil contained in gearbox case pressure flows from hydraulic pressure channel axially from valve seat (72a) along concave part (72b) of valve box (72) to go out of outlets (76a and 76b) and into hydraulic pressure feed channel of valve body (40). Ball (73) moves axially between valve seat (72a) and lock section (75a).
EFFECT: longer life, lower pressure losses.
