Disclosed herein an electronic brake system includes a hydraulic pressure supply device including a first pressure chamber and a second pressure chamber partitioned by a hydraulic piston, and a hydraulic control unit, wherein the hydraulic control unit comprises a first hydraulic flow path connecting the first pressure chamber and one of the first and second hydraulic circuits, a second hydraulic flow path branched from the first hydraulic flow path to connect to the other one of the first and second hydraulic circuits, a third hydraulic flow path branched from the first hydraulic flow path on upstream side of a branch point of the second hydraulic flow path to connect the second pressure chamber, and a fourth hydraulic flow path branched from the first hydraulic flow path on upstream side of a branch point of the third hydraulic flow path to connect the third hydraulic flow path.

Provided is an electronic brake system including: a reservoir in which a pressurized medium is stored; an integrated master cylinder including a simulation chamber, a simulation piston provided in the simulation chamber to be displaceable by a brake pedal, a master chamber, a master piston provided in the master chamber to be displaceable by a displacement of the simulation piton or a hydraulic pressure of the simulation chamber, an elastic member provided between the simulation piston and the master piston, a piston spring elastically supporting the master piston, a simulation flow path connecting the simulation chamber to the reservoir, and a simulator valve provided in the simulation flow path to control a flow of a pressurized medium; a hydraulic pressure providing unit provided to generate a hydraulic pressure by operating a hydraulic piston according to an electrical signal output in response to a displacement of the brake pedal; a hydraulic pressure control unit including a first hydraulic circuit provided to control the hydraulic pressure to be transferred to two wheel cylinders, and a second hydraulic circuit provided to control the hydraulic pressure to be transferred to other two wheel cylinders; an electronic control unit configured to control valves based on hydraulic pressure information and displacement information of the brake pedal; a backup flow path connecting the simulation chamber to the first hydraulic circuit; an auxiliary backup flow path connecting the master chamber to the backup flow path; and an inspection valve provided in the auxiliary backup flow path to control a flow of the pressurized medium.

An apparatus and kit are provided for remotely controlling the flow of a valve in a faucet or shower. The user may remotely control flow by actuating a foot pedal, which pulls a cable causing the valve to open. When the cable is released, springs force the valve closed. Temperature may be remotely controlled as well by the actuation of a separate foot pedal, in which rotation of the foot pedal is transferred by cables to cause rotation of the valve and the corresponding temperature change of the flow.

A high pressure valve includes a lever and a variable force generator for facilitating control of opening and closing the valve at high pressures. The high pressure valve includes a housing having a chamber providing fluid communication between a first port and a second port, a pin movable within the chamber between an open position and a closed position. A first end of a lever is coupled to the pin and a second end of the lever is coupled to a variable force generator. The lever pivots about a pivot point. A controller coupled to the variable force generator is configured to adjust a force applied to the second end of the lever by the variable force generator to control the movement of the pin between the open position and the closed position.
