一体型減衰調整弁
Document Type and Number:
Japanese Patent JP2006514231
Kind Code:
A
Abstract:
A variable damper assembly ( 10 ) includes a cylinder head ( 42 ) with multiple valves ( 50 ) selectively blocking corresponding flow paths ( 54 ) to provide multiple dampening rates. Hydraulic fluid passing through flow paths ( 54 ) within the cylinder head ( 42 ) are selectively opened and closed to provide a desired dampening rate. The cylinder head ( 42 ) includes an upper part ( 44 ) and a lower part ( 46 ). The valves ( 50 ) are mounted within the upper part ( 44 ) of the cylinder head ( 42 ). Each of the valves ( 50 ) includes a plunger ( 56 ) extending into flow passages ( 54 ) defined within the lower part ( 46 ) of the cylinder head ( 42 ). Actuation of the valves ( 50 ) within the cylinder head ( 42 ) selectively opens and closes specific flow paths ( 54 ) within the lower part ( 46 ) of the cylinder head ( 42 ) to control the flow of fluid between upper and lower portions ( 14,16 ) of a dampening chamber ( 12 ).
