1. A shock absorber comprising:
- a housing;
a piston rod slidably disposed within said housing;
a first rod guide member secured within a first portion of said housing so as to be concentrically disposed about at least a portion of said piston rod;
a second rod guide member secured within said housing adjacent said first rod guide member so as to be concentrically disposed about at least another portion of said piston rod;
an electronically controlled valve assembly disposed within said second rod guide member and in communication with said first rod guide member;
a seal separate from said first and second rod guide members directly engaging said piston rod;
a circuit board removably secured within an annular channel in said first rod guide member, said circuit board in communication with said electronically controlled valve assembly; and
a first bushing directly engaging said piston rod, said first bushing being disposed within an aperture defined by said first guide member.

Abstract
A shock absorber has a housing with a piston rod assembly disposed therein. A first rod guide member is secured within a first portion of the housing so as to be concentrically disposed about at least a portion of the piston rod assembly. A second rod guide member is secured within the housing adjacent the first rod guide member so as to be concentrically disposed about at least another portion of the piston rod assembly. An electronically controlled valve assembly is disposed within the second rod guide member and is in communication with the first rod guide member.

12. A shock absorber comprising:
-
a housing defining a first fluid chamber; a piston rod sliding in said housing, said piston rod defining a second fluid chamber; a rod guide for guiding said piston rod in said housing, said rod guide further comprising; an upper rod guide member; a lower rod guide member adjacent said upper rod guide member, each of said upper and lower rod guide members having a central aperture slidably receiving said piston rod; an electronically controlled valve assembly arranged within said lower rod guide member and in communication with said upper rod guide member, said electronically controlled valve assembly metering a fluid flow between said first fluid chamber and said second fluid chamber; a seal separate from said upper and lower rod guide members directly engaging said piston rod; a circuit board removably secured within an annular channel in said first rod guide member, said circuit board in communication with said electronically controlled valve assembly; and a first bushing directly engaging said piston rod, said first bushing being disposed within said aperture defined by said upper guide member. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
