A brake unit having a container which serves for accommodating working fluid and which is arranged with at least one connector piece in a receiving bore and which is sealed off by a sealing element which extends radially around the connector piece. In order to offer a simple, inexpensive and pressure-tight interface between connector piece in a receiving bore, it is proposed that a form fit transversely with respect to the direction of the longitudinal axis of the connector piece is formed by a displacement of the material of the sealing element during the installation of the connector piece in the receiving bore.

Disclosed herein an electronic brake system includes a first block comprising a master cylinder having a first master piston connected to a brake pedal and a first master chamber whose volume is changed by a displacement of the first master piston; a second block comprising a pedal simulator, a hydraulic pressure supply device that generates a hydraulic pressure by operating a hydraulic piston according to an electrical signal, and a hydraulic control unit comprising a first hydraulic circuit that controls a hydraulic pressure transferred to two wheel cylinders and a second hydraulic circuit that controls a hydraulic pressure transferred to the other two wheel cylinders, the second block disposed to be spaced apart from the first block; a plurality of electronic control units (ECUs) that controls various devices and valves based on hydraulic pressure information and displacement information of the brake pedal; and a connection line having one end connected to the first block and the other end connected to the second block; wherein the connection line has one end connected to the first master chamber and the other end thereof connected to the pedal simulator side.

A brake system with a wheel brake has a fluid reservoir and a valve assembly in fluid communication with the reservoir via a first conduit. The valve assembly is in fluid communication with the wheel brake via a second conduit. The valve assembly includes a bypass valve which only permits fluid flow from the first conduit to the second conduit when the fluid pressure within the first conduit is above a predetermined pressure level above atmospheric pressure. The valve assembly further includes a check valve in a parallel path arrangement relative to the bypass valve such that the check valve permits fluid flow from the second conduit to the first conduit, and prevents fluid flow from the first conduit to the second conduit. The brake system further includes a first source of pressurized fluid providing fluid pressure for actuating the wheel brake, wherein the first source of pressurized fluid is selectively in fluid communication with the second conduit.

An apparatus for improving efficiency of a turbocharger engine including a turbocharger configured of a turbine rotated by discharge force of exhaust gas transferred from an exhaust manifold, and a compressor rotated coaxially with the turbine to compress intake air applied to an engine is provided. The turbine includes a turbine housing and a turbine wheel. The apparatus includes an auxiliary wheel that is formed at one side of the turbine wheel and an air compressor rotated by being connected to a crankshaft of the engine to generate compressed air. A valve connects between the air compressor and an air tank to transfer the compressed air to the air tank, and transfers, when charging of the air tank is completed, the compressed air to the auxiliary wheel side to increase torque of the turbine wheel.

In the present invention, when a first protrusion of a shaft abuts on a guide face thereby pressing a first valve element toward the top as seen in the drawing, the guide face is separated from a cylinder seat face, and a large-diameter oil passage is opened. At this time, when the first protrusion abuts on the guide face thereby driving the first valve element to the position where the valve opens, the first valve element is also pressed in a direction perpendicular to the reciprocating direction of the first valve element because the guide face has a spherical surface or a tapered surface. Thus, the first valve element is supported at two points, point E and point F or G, thereby dampening vibrations.
