Antilock liquid-pressure control apparatus

An antilock liquid-pressure control apparatus comprising:

• a first liquid-pressure control mechanism, an inner space thereof being partitioned into a first liquid chamber and a second liquid chamber by a piston;
• a second liquid-pressure control mechanism, an inner space thereof being partitioned into a liquid chamber and a spring container by a piston;
• wherein said second liquid chamber in said first liquid-pressure control mechanism is communicatively connected to a wheel cylinder and a pressure chamber of a master cylinder through a valve mechanism which closes a flow path only when an antilock control is executed, said first liquid chamber in said first liquid-pressure control mechanism is communicatively connected to a discharge port of a liquid pressure pump and said liquid chamber in said second liquid-pressure control mechanism through a flow control valve and further to a reservoir through a decay valve, and said spring container in said second liquid-pressure control mechanism communicates with said pressure chamber of said master cylinder, and
• wherein in a pressure reduction mode of said antilock control, brake liquid is sucked from said first liquid chamber by a liquid pressure pump, and said sucked brake liquid is accumulatively pressurized in said liquid chamber of said second liquid-pressure control mechanism, and said brake liquid is returned from said spring container to said master cylinder, and in a pressure reapplication mode of said antilock control, said brake liquid is supplied from said liquid chamber of said second liquid-pressure control mechanism to said first liquid chamber, through said flow control valve.
