Abstract
Vorgeschlagen ist ein hydraulisches Abstützelement (1) für einen Ventiltrieb einer Brennkraftmaschine, mit einem Gehäuse (2), in dessen Bohrung (3) axial beweglich ein Druckkolben (4) sitzt, welcher mit seinem Kopf (5) einen Rand (6) des Gehäuses (2) überragt und in seinem Inneren (7) einen Vorratsraum (8) für Hydraulikmittel einschließt, wobei zwischen einer kopffernen Stirn (9) des Druckkolbens (4) und einem Boden (10) des Gehäuses (2) ein Hochdruckraum (11) für das Hydraulikmittel liegt, welcher durch ein an der Stirn (9) des Druckkolbens (4) angeordnetes Rückschlagventil (12) mit dem Hydraulikmittel versorgbar ist, wobei am Außenmantel (13) des Gehäuses (2) zumindest eine Einlassbohrung (14) für das Hydraulikmittel angeordnet ist, welche in eine Ringnut (15) oder einen Längspfad in der Bohrung (3) des Gehäuses (2) mündet, die mit einer Ringnut (16) oder einem Längspfad am Außenmantel (17) des Druckkolbens (4) kommunizieren, die wiederum mit wenigstens einer Einlaufbohrung (18) im Druckkolben (4) in den Vorratsraum (8) in Fluidverbindung stehen und wobei die Einlassbohrung (14) im Gehäuse (2) axial unmittelbar unterhalb dessen Randes (6) liegt.Proposed is a hydraulic support element (1) for a valve train of an internal combustion engine, with a housing (2) in the bore (3) axially movable a pressure piston (4) sits, which with its head (5) has an edge (6) of the housing (2) surmounted and in its interior (7) includes a reservoir (8) for hydraulic means, wherein between a head distant end (9) of the pressure piston (4) and a bottom (10) of the housing (2) has a high pressure chamber (11) for the hydraulic means is located, which can be supplied with the hydraulic means by a check valve (12) arranged on the end (9) of the pressure piston (4), wherein at least one inlet bore (14) for the hydraulic medium is arranged on the outer casing (13) of the housing (2) is, which in an annular groove (15) or a longitudinal path in the bore (3) of the housing (2) opens, which communicate with an annular groove (16) or a longitudinal path on the outer jacket (17) of the pressure piston (4), which in turn at least one inlet fbohrung (18) in the pressure piston (4) in the reservoir (8) are in fluid communication and wherein the inlet bore (14) in the housing (2) axially directly below the edge (6).
Description
Vorgeschlagen ist ein hydraulisches Abstützelement für einen Ventiltrieb einer Brennkraftmaschine, mit einem Gehäuse, in dessen Bohrung axial beweglich ein Druckkolben sitzt, welcher mit seinem Kopf einen Rand des Gehäuses überragt und in seinem Inneren einen Vorratsraum für Hydraulikmittel einschließt, wobei zwischen einer kopffernen Stirn des Druckkolbens und einem Boden des Gehäuses ein Hochdruckraum für das Hydraulikmittel liegt, welcher durch ein an der Stirn des Druckkolbens angeordnetes Rückschlagventil mit dem Hydraulikmittel versorgbar ist, wobei am Außenmantel des Gehäuses zumindest eine Einlassbohrung für das Hydraulikmittel angeordnet ist, welche in eine Ringnut oder einen Längspfad in der Bohrung des Gehäuses mündet, die mit einer Ringnut oder einem Längspfad am Außenmantel des Druckkolbens kommunizieren, die wiederum mit wenigstens einer Einlaufbohrung im Druckkolben in den Vorratsraum in Fluidverbindung stehen.Proposed is a hydraulic support member for a valve train of an internal combustion engine, with a housing in the bore axially movable a pressure piston sits, which projects beyond an edge of the housing with its head and includes in its interior a reservoir for hydraulic fluid, wherein between a head distant forehead of the pressure piston and a bottom of the housing is a high pressure chamber for the hydraulic fluid, which is supplied by a arranged on the end of the pressure piston check valve with the hydraulic means, wherein on the outer casing of the housing at least one inlet bore for the hydraulic means is arranged, which in an annular groove or a longitudinal path in the bore of the housing opens, which communicate with an annular groove or a longitudinal path on the outer surface of the pressure piston, which in turn are in fluid communication with at least one inlet bore in the pressure piston in the reservoir.
Die
Aufgabe ist es daher, ein Abstützelement ohne den zuletzt genannten Nachteil zu schaffen.The object is therefore to provide a support element without the last-mentioned disadvantage.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Einlassbohrung im Gehäuse axial unmittelbar unterhalb dessen Randes liegt.According to the invention, this object is achieved in that the inlet bore in the housing is located axially directly below its edge.
Somit liegt ein axial deutlich erhöhtes Reservoir für das Hydraulikmittel vor. Eine Unterkante der „hochgelegten“ Einlassbohrung bestimmt den niedrigsten Level für das Hydraulikmittel im Abstützelement. Thus, there is an axially significantly increased reservoir for the hydraulic fluid. A lower edge of the "raised" inlet bore determines the lowest level for the hydraulic fluid in the support member.
Wird im Druckkolben noch ein Umlaufturm für das Hydraulikmittel verbaut, so ist ein weiterer Beitrag in Richtung Auslaufsicherheit oder Erhöhung der Hydraulikmittelsäule im Abstützelement geleistet.If a circulation tower for the hydraulic fluid is still installed in the pressure piston, then another contribution is made in the direction of leakage safety or increasing the hydraulic fluid column in the support element.
