Two Pumping Dual-Chamber Brake Valve Introduction
Since 2006 until now,the company organizes experts experts and technical staff in the industry and invests massive funds in order to carry on the market investigation and R&D product technology for the technology field of brake valve.A series of patented products developed apply to 80% of the domestic load models,after loading tests thousands of times,to get the full recognition and widely welcomed.Currently,the company has a number of patented products with proprietary brands.This series of patented product is a new type of brake valve which is developed by overcoming existing technical defects and summarized and absorb advantages,the application to 5 invention patents,7 utility model patents and 8 patent applications:"Single-in and Multiple-out Secondary Electromagnetic Supercharge Master Cylinder"(Patent Number:ZL 2006 10107240.7),"Three-in and Multiple-out Secondary Electromagnetic Supercharge Master Cylinder"(Patent Number:ZL 2006 10107239.4),"Electromagnetic Control of Dual-chamber Parallel Secondary Supercharge Brake Master Cylinder"(Patent Number:ZL 2006 10107095.2),"Integral Emergency Brake Pedal"(Patent Number:ZL 2007 20091240.2),"Emergency Brake Pedal"(Patent Number:ZL 2007 20182127.5),"Two Pumping Dual-Chamber Parallel Brake Valve"(Patent Number:ZL 2010 20193191.5),"Two Pumping Brake Valve"(Patent Number:ZL 2010 20193133.2).It has been made actual improvements for the existing two-lane balance by adopting comparative scientific technology which combines electric with loop voltage.What's more,it solves the issue that it is difficult to achieve two-lane balance in the "theory".Now our product achieves two-lane balance in practice and then improves braking safety,while has energy-saving and consumption-reducing function.At present, this technology has reached the international leading level and its perspective is wide.
