A shock absorber is provided that includes a housing having an inner wall defining a working fluid chamber and an outer wall spaced outwardly from the inner wall defining a fluid reservoir. Either a compression head or an inner cylinder head may be arranged at an end of the housing. The head extends radially from a first portion interior of the inner wall to a second portion exterior of the inner wall with the head separating the working fluid chamber and the fluid reservoir. The head includes a passageway extending between the first and second portions fluidly interconnecting the working fluid chamber and the fluid reservoir. A valve is disposed about the inner wall and is arranged in the fluid reservoir. The valve has an annular sealing portion adjacent to the second portion for obstructing fluid flow through the passageway in a closed position and spaced from the second portion in an open position. A toroidal solenoid has a central opening with the inner wall disposed within the central opening. The solenoid concludes an electric coil generating magnetic flux on either the inner wall or the valve for generating a closing force against the second portion with the sealing portion. Alternatively, the valve and toroidal solenoid may be arranged outside of the fluid reservoir about either the piston rod or the lower mount.
