A hydraulic unit for a slip controller of a hydraulic vehicle brake system includes an electric motor, a plurality of hydraulic pumps, a hydraulic block, a plurality of solenoid valves, a rotation angle sensor, an electronic control unit, and a valve cover. The electric motor is positioned on a narrow side of the hydraulic block, and is configured to drive the hydraulic pumps. The electronic control unit includes a contacting mechanism, and is positioned in the valve cover. The electric motor and the solenoid valves are arranged so that the electric motor and electromagnets of the solenoid valves protrude to approximately a same extent from the hydraulic block to enable simple commutation with the rotation angle sensor and the contacting mechanism of the electronic control unit.

A flare-type brake line assembly includes (a) a brake tube having a flare with a first sealing surface, (b) a brake component having a port with a second sealing surface and (c) a tube nut to secure the brake tube and brake component together. At least one of the two sealing surfaces is treated to increase the coefficient of friction between those surfaces. A related method is also disclosed.

Disclosed is a solenoid valve for a brake system. The solenoid valve includes a valve housing installed in a bore of a modulator block and configured to include an internal flow path, a valve sheet provided at the internal flow path of the valve housing and configured to include an orifice, an armature configured to be slidably moved up and down by a magnet core and to include an opening or closing sphere configured to selectively open or close the orifice, a sleeve configured to accommodate the armature therein and to have one end coupled to the valve housing and the other end at which the magnet core is provided, and a damper guide provided at the internal flow path of the valve housing to come into contact with and surround the armature.

Check valves are disclosed and include a housing defining an internal cavity having a first seat and a second seat, and a seal member within the internal cavity translatable between a closed position against the first seat and an open position against the second seat. The second seat has a middle axis transverse to a plane of a longitudinal cross-section of the housing and has a shortest finger positioned to either the left or to the right of the middle axis. The seal member is seatable against the second seat at an angle or in a deflected position against the plurality of fingers, thereby defining a longer distance of travel to reach the closed position for a portion of the check valve disc that is associated with the position of the shortest finger relative to other portions of the check valve disc.

A hose repair kit includes a retaining sleeve having a first opening to receive an end of a hose. There is a swivel coupling inserted into a second end of the hose retaining sleeve to engage with the hose. The swivel coupling includes a first annular member with an annular barb at one end and a socket to receive a key at a second end. There is an annular retaining ring groove with a retaining ring therein. A second annular member receives, within an internal bore having an annular recess, the first annular member and the retaining ring engages the annular recess to secure the first annular member to the second annular member. The surface of the bore is frusto-conically shaped allowing the retaining ring to be compressed as it travels into the bore until it reaches the annular recess and expands into and is seated in the annular recess.
