ABSTRACT:
An improved shock absorbing device includes a compression head assembly of simpler, less expensive, and more efficient design than prior art compression head assemblies. The compression head assembly of this invention includes an improved valve, a base plate, an annular disk valve, first and second bias members, and a valve stop. The valve is made of a generally elongated, preferably cylindrical, body with an outwardly extending flange having one or more passages therethrough. The base member has a disk shape with an opening centrally therethrough. The valve stem is assembled in relation to the base member such that the generally cylindrical body is inserted through the opening. The outwardly extending flange of the valve abuts against and forms a seal with the base member. An annular disk valve is assembled over the generally cylindrical body of the valve stem so as to abut the flange portion of the valve and close the passages through the flange. A first bias member urges the annular disk valve into abuttment with the flange, thereby maintaining a closure of the passages in normal orientation. A second bias member urges the valve flange into abuttment and sealing contact with the base member. The valve stop maintains the first and second bias members between in biased position.
