121 BRAKING-FORCE GENERATOR US13943079 2013-07-16 US20140020377A1 2014-01-23 Yuki ITO
In a braking-force generator: a master cylinder generates first braking force corresponding to an operational input through a manipulator; a hydraulic-pressure generator connected to the master cylinder through a shutoff valve generates second braking force corresponding to the operational input through the manipulator when the shutoff valve is closed; an abnormality detector repeatedly determines whether or not an operational state of the hydraulic-pressure generator is abnormal; and a controller prohibits generation of the second braking force, opens the shutoff valve, and transmits the first braking force to the hydraulic-pressure generator, when the operational state is abnormal. In the case where the abnormality detector determines that the operational state changes from an abnormal state to a normal state while manipulation with the manipulator is being performed, the controller keeps prohibition of the generation of the second braking force and keeps the shutoff valve open until the manipulation is terminated.

131 ANNULAR VALVE US13810563 2012-02-09 US20130205986A1 2013-08-15 William Rampen; Uwe Stein
An annular valve (1) has an annular valve member (4) and inner and outer annular valve seats (12, 14). Inner and outer sealing ridges (8, 10) are formed either on the annular valve member or on the valve seats. The inner sealing ridges are more resistant to plastic deformation than the outer sealing ridges. They may be thicker, or made from a harder material. Thus, the annular valve better resists damage arising from greater plastic deformation of the inner sealing ridge than the outer sealing ridge due to greater forces (Fi, Fo) acting on the inner sealing ridge than the outer sealing ridge in use.
