Abstract (en)
[origin: US4876997A] A self-adjusting hydraulic valve tappet arranged in a guide bore of a cylinder head of an internal combustion engine against whose one end face a cam abuts and whose other end face lies against a valve stem which avoids the disadvantages of the prior art and achieves a durable self-tightness of the sleeve with respect to the oil reservoir independently of the deflections of the end member by using simple constructional and particularly hardly more expensive means.
