Patent number: 10495232Abstract: The invention relates to a dual path dual purging system and valve assembly for turbo boosted engines. More specifically, the invention provides an integrated valve assembly connected to facilitate the operation of the low flow valve as a pilot valve for the high flow valve and a system to implement it on turbocharged or supercharged engines. The invention relates to a dual path dual purging system with two purge valves connected to facilitate the use of the low flow valve to be operated as a pilot valve for the high flow valve. This smart routing provides pressure compensation for the high flow valve, when the valve is enabled. This decreases the requirement of force for the high flow valve and gives an option to install a smaller cost efficient solenoid valve.Type: GrantFiled: December 29, 2016Date of Patent: December 3, 2019Assignee: Padmini VNA Mechatronics Pvt.

Patent number: 9027590Abstract: A ventilation arrangement for the head space of the fuel tank of a vehicle comprises a switchable main valve intended for adjusting an arbitrary pressure in the head space of the tank. By way of the opening position of the main valve, a connection between a connection (5) intended for connection to the head space and a connection (6) intended for connection to the surrounding atmosphere is established, wherein the main valve is assigned a pilot valve, which opens during a first path element of a switching movement, wherein the main valve only opens following this first path element. Because of the small cross section of the pilot valve and the pressure relief that materialized through its opening, the switching power can be reduced and a smaller size drive can be employed.Type: GrantFiled: September 14, 2012Date of Patent: May 12, 2015Assignee: A.
