Abstract

Corpo di punteria idraulica costituito da un elemento a forma di manicotto e da un disco superiore ad esso vincolato, in cui l'elemento a manicotto (2) è sostanzialmente costituito da una parete esterna tubolare relativamente sottile che superiormente prosegue verso l'interno con un tratto orizzontale (5) formante una spallatura di notevole estensione alla quale si salda il detto disco superiore e verso il basso con un tratto conico (6), terminante con un tratto tubolare cilindrico (8) che costituisce la sede di accoglimento dei componenti mobili della punteria, in corrispondenza del tratto conico (6) venendo così formato un serbatoio esterno (7) per olio di dimensioni ridotte, un condotto (20) di alimentazione dell'olio sboccando nella parte superiore del detto serbatoio (7). Nella parte superiore della parete dell'elemento a manicotto (2) è formato un ispessimento (18) entro il quale viene realizzato il detto condotto (20) di alimentazione dell'olio mentre una gola o scanalatura (22) di raccolta dell'olio è ottenuta per rullatura sulla superficie esterna della detta parete tubolare mentre sulla superficie interna di questa parete viene formata una protuberanza anulare (24).Hydraulic tappet body consisting of a sleeve-shaped element and an upper disk constrained thereto, in which the sleeve element (2) is substantially constituted by a relatively thin tubular external wall which continues inwards towards the inside with a horizontal section (5) forming a shoulder of considerable extension to which said upper disc is welded and downwards with a conical section (6), ending with a cylindrical tubular section (8) which constitutes the seat for receiving the mobile components of the tappet, in correspondence with the conical section (6), thus forming an external tank (7) for oil of reduced dimensions, a conduit (20) for feeding the oil, opening into the upper part of said tank (7). In the upper part of the wall of the sleeve element (2) a thickening (18) is formed within which said oil supply conduit (20) is made while an oil collection groove (22) is obtained by rolling on the external surface of said tubular wall while on the internal surface of this wall an annular protuberance (24) is formed.
