ABSTRACT:
The invention concerns a regulable shock-absorption valve system for the dashpot in a motor vehicle. It has two shock-absorption valves. Each valve consists of an electromagnetic bolt that slides back and forth and operates in conjunction with at least one port and of a pressure-sensitive valve for the suction stage and for the compression stage, mutually coaxially accommodated in an essentially cylindrical housing and capable of communicating by way of hydraulic-fluid channels. The pressure-sensitive valves (7 & 8) in accordance with the present invention rest on a simple or complex component (15) with its ends permanently or temporarily secured in a bore that extends through the center of the pole cores (17 & 18) of the electromagnets (11) that actuate the bolts (5 & 6). The advantages of the present invention are direct transmission of the shock-absorption forces and simpler assembly of the system.
