Valeo's solenoid valve mechanism "SVA". The left side is the standard size and the right side is the exploded sample for display. It was first made public at the Frankfurt Motor Show held in September 2005.
Valeo, France, exhibited the solenoid valve mechanism "Smart Valve Actuation (SVA)" at the Tokyo Motor Show. Instead of using a cam when opening and closing the valve, it is controlled by an electromagnetic actuator. In addition to optimal control of the valve opening and closing timing and valve opening time according to the number of engine revolutions, it is also easy to achieve cylinder intermittent functions, etc., so that fuel consumption and exhaust gas purification performance can be improved by 20%, and when rotating at low speed The torque is increased by about 15-20%.
At present, Valeo is developing two kinds of electromagnetic valves, one is "Full Camless" which can eliminate the suction and exhaust cam at the same time, and the other is "Half Camless" which only saves the suction cam. In addition to the use of two electromagnets used to open and close the valve instead of the omitted cam, and the addition of armatures and sensors and other components, the weight of the double solenoid valve mechanism exhibited this time reached about 1.8kg. In addition, a control unit with a 32-bit processor is required.
The company has jointly developed SVA institutions with a number of car manufacturers, and plans to start mass production in 2009.
Roller shutter door , also known as "shutter door", lots of panel pieces connected together, fixed in the guide rail , take above reel as the center of rotation.
Roller shutter door is used for commercial facades, garages, shopping malls, hospitals, factories and mines and other public places or residential.Electric roller shutter door, especially for large openings, inconvenient to install the ground door , quick opening effect. Such as for the garage door, shopping mall fire shutter door.
Opening methods: Handing driving mode
