Vibration damper valve assembly with switchable bypass

A vibration damper valve assembly comprising:

• a valve main body that includes a first surface and a second surface that is opposed to or opposite the first surface;
• a first main stage flow path that extends through a first fluid passage from the first surface to the second surface in a through-flow direction;
• a second main stage flow path that extends through a second fluid passage from the second surface to the first surface in a through-flow direction;
• a first disc valve pack that is disposed on the first surface for controlling flow through of the second main stage flow path;
• a second disc valve pack that is disposed on the second surface for controlling flow through the first main stage flow path;
• a first main stage bypass flow path that extends through one of the fluid passages from the first surface to the second surface in a through-flow direction;
• a second main stage bypass flow path that extends through one of the fluid passages from the second surface to the first surface in a through-flow direction,
• wherein at least one of:
• the second fluid passage of the second main stage flow path is a fluidic connection to the fluid passage of the first main stage bypass flow path, wherein the through-flow direction of the second main stage flow path is opposed to the through-flow direction of the first main stage bypass flow path, wherein the first disc valve pack controls flow through of the second main stage flow path and of the first main stage bypass flow path, or
• the first fluid passage of the first main stage flow path is a fluidic connection to the fluid passage of the second main stage bypass flow path, wherein the through-flow direction of the first main stage flow path is opposed to the through-flow direction of the second main stage bypass flow path, wherein the second disc valve pack controls the flow through of the first main stage flow path and of the second main stage bypass flow path;
• wherein at least one of:
• the second fluid passage of the second main stage flow path is a fluidic connection to the fluid passage of the first main stage bypass flow path, wherein the through-flow direction of the second main stage flow path is opposed to the through-flow direction of the first main stage bypass flow path, wherein the first disc valve pack controls the flow through of the second main stage flow path and of the first main stage bypass flow path, or
• the first fluid passage of the first main stage flow path is a fluidic connection to the fluid passage of the second main stage bypass flow path, wherein the through-flow direction of the first main stage flow path is opposed to the through-flow direction of the second main stage bypass flow path, wherein the second disc valve pack controls the flow through of the first main stage flow path and of the second main stage bypass flow path.
