Abstract: The present invention relates to a hydraulic control device for an antilock brake system, which is capable of maintaining a certain amount of braking performance even in the event of a disturbance or repeated use, by enabling the restriction of the displacement of a control bolt to a certain range. Therefore, through the present invention, braking ability is not lost under any circumstances, and accidents caused by a loss of braking function due to the malfunctioning of a hydraulic control device for an antilock brake system can be averted.

Abstract: A damper hole having a large-diameter section is formed inside a body which is made of metal. A flange which fits in the large-diameter section is formed in a damper which is made of rubber and is received in the damper hole. The flange defines a cushion chamber in the large-diameter section. A gap for letting air restrictively discharge from the cushion chamber is formed between an outer periphery of the flange and an inner periphery of the large-diameter section. Motion energy of a moving object colliding with the damper is absorbed by both elasticity produced by the compressed damper and an air cushion effect produced by the flange and the cushion chamber.

Abstract: A shock strut includes a relief device that reduces the internal pressure within a sealed chamber of the shock strut when a load condition that exceeds a maximum operating load condition is encountered. The reduced pressure permits a telescopically moving piston of the shock strut to be received into a corresponding cylinder to an amount that increases the structural capability of the shock strut, especially with respect to applied side loads that generate bending and shearing stresses in the shock strut. In one embodiment, the reduced pressure permits the piston to “bottom out” relative to the cylinder, which is a condition not otherwise achievable without the relief device. This additional stroke achievable by the piston reduces or eliminates the need to reinforce and thus add weight to the shock strut because of higher load condition design requirements.

The service brake is formed so that, when the service brake is operated, a first control element (120) is moved towards the brake elements (140, 141) in such a way that a brake chamber (150) is fluidically connected to the inlet manifold (180) and thus ensures an additional oil supply from the oil chamber (130).
