Abstract

Foreliggende oppfinnelse vedrører en væsketrykkaktiverbar sekvensventil til bruk ved generering av oscillerende aksiale hammerbevegelser, der sekvensventilen omfatter en ventilkonstruksjonen som omfatter en ytre rørmantel (1) som forbundet med adaptere (3) og (5) i hver ende, en indre langstrakt konsentrisk opplagret sylindrisk rørdel (1 2) omfattende en ventilflate (1 8), et ringelement (7) omfattende en ventilflate (8) samt en ringventil (17) omfattende en ventilflate (22). Oppfinnelsen er særpreget ved at den væsketrykkaktiverbare sekvensventils vesketrykkpåvirkede ringarealer (A2, A3, A4) og trykkdifferanse tilfredsstiller følgende relasjon: A3/A4 (1- Fs /A2 P) > 1 der: P er et væsketrykk som føres inn gjennom hull (9, 20) fra strengdelen (12) og genererer en aksialkraft (Fh) ved å virke over ringarealet (A2), og Fs er kraften som genereres i en fjær (14).
