Claims

[Claims for Utility Model Registration] Consisting of two cup-shaped members, an inner and outer part, and a gap provided between the end walls of both members, a liquid flow path formed in a cylinder block, and a supply path formed in both said members. In the hydrovalve tappet configured to communicate through a circumferential wall of the inner member, the feed passage may be formed between three or more through holes provided at equal intervals around the circumference of the circumferential wall of the outer member, and three or more through holes provided at equal intervals around the circumference of the circumferential wall of the inner member. It is composed of a groove, a guide hole provided in the flesh part of the inner member so as to communicate the circumferential groove and the gap, and a check ball accommodated in an opening on the gap side of the guide hole so as to be openable and closable, and A hydrovalve tappet characterized in that the liquid flow path is opened so as to intersect with the tappet insertion hole in a tangential direction so as to always communicate with one of the through holes provided in the outer member.
