Definitions
- the invention relates to a double-flow hydraulic support element for a switchable finger follower of a valve train of an internal combustion engine, with a pot-like housing which can be installed in a cylinder head of an internal combustion engine, in which a piston is arranged axially movably in an axial bore of the housing coaxial with the longitudinal center axis of the support element.
- the piston consists of a hollow cylindrical pressure part and an axially adjoining cup-shaped working part, in which at least one head of the pressure part of the piston serves as a support for the switchable rocker arm and protrudes axially beyond a housing edge, in which the end face the head of the piston is formed an opening for flowing through a hydraulic means for applying a hydraulically controllable coupling device in the switchable rocker arm, wherein the housing has a first radial passage and axially spaced therefrom a second has radial passage for hydraulic means, and in which on the support a hydraulic raulaus Morgans observed for the finger follower is formed, said lash adjuster comprises a ball check valve.
- a double-flow support element for a switchable drag lever of a valve drive of an internal combustion engine which has two separate flow paths for a hydraulic medium in one housing.
- the first flow path is used to supply a hydraulic lash adjuster, while via the second flow path, the supply of coupling means in an overlying, switchable rocker arm takes place with the hydraulic fluid.
- the hydraulic separation of the two flow paths takes place by means of a cap-shaped element, which is inserted into a hollow pressure piston of the support element.
- a check valve within the hydraulic lash adjuster is formed with a ball which, in the closed position of the check valve, closes a bore in a bottom of a working piston.
- a valve spring pushes the ball axially with a defined mechanical biasing force against the open end of the bore in the piston head, wherein the valve spring between the ball and a cup-shaped cap is supported.
- a radially outwardly directed flange of the pot-shaped cap bears with a defined force on a lower-side axial recess of the working piston, wherein a compression spring for generating the necessary pressure force between the flange of the cap and a bottom surface of a cylinder space of the housing of the support member is supported.
- a similar support element is known from DE 10 2006 045 017 A1.
- a disadvantage of these support elements is that above the cap-shaped element in the pressure piston, a comparatively large dead volume for receiving hydraulic fluid is formed. This leads to a non-optimal response of the coupling agent in the cam follower and this leads to comparatively imprecise timing in the valve train.
- DE 10 2004 006 903 A1 a single-flow hydraulic support element is known with which only a clearance compensation can be carried out hydraulically on a non-shiftable rocker arm. This clearance compensation also works by means of a ball check valve, which is arranged in the axially lower region of the hydraulic support element and is acted upon by a reservoir in the support element with hydraulic fluid.
- the storage space is limited in this support element by a deflection sleeve, which is arranged coaxially in an axially extending cavity of the pressure piston of the support element and the same with a larger diameter portion on the inner circumferential surface thereof.
- the deflection sleeve has an inflow opening for hydraulic fluid.
- the supply of the reservoir with hydraulic fluid via a radial bore in the housing and a radial bore in the pressure piston of the hydraulic support element. Before there, the hydraulic fluid passes through a hollow cylindrical climbing path, which is formed between the outer wall of the Umlenkhülse and the inner wall of the pressure piston, to the check valve remote inflow opening in the Umlenkhülse, and from there into the storage room.
- a radial vent hole is formed in the pressure piston.
- this hydraulic support member of DE 10 2004 006 903 A1 can be removed that passes after the influx of hydraulic fluid through the radial bore in the housing and the radial bore in the pressure piston this in the hollow cylindrical climbing path.
- a first portion of the optionally contained in the supplied hydraulic fluid air is discharged through the radial vent hole in the open.
- the supplied hydraulic fluid then passes through the axial opening in the Umlenkhülse in the reservoir, which over a relatively axially long range of the Deflection sleeve is radially limited.
- the accumulated there hydraulic fluid is there already relatively calm and free of air bubbles.
- the invention is based on the object of presenting a double-flow hydraulic support element in which a hydraulic clearance compensation device and a second flow path coupling means for a switchable rocker arm resting on the support element can be supplied with a hydraulic medium via a first flow path.
- the new support element should allow a particularly precise and delay-free control of the coupling means of the finger lever.
- the invention is based on the recognition that undesirable delay times in the operation of actuators in a hydraulic system can be reduced by reducing the volumes of the hydraulic circuits involved in the actuation.
- the invention accordingly relates to a double-flow hydraulic support element for a switchable rocker arm of a valve train of an internal combustion engine, with a pot-like housing which can be installed in a cylinder head of an internal combustion engine, in which an axially movable piston in an axial bore of the housing coaxially to the longitudinal center axis of the support element is arranged, in which the piston of a hollow cylindrical pressure member and an axially subsequent topfför- migen working part, in which at least one head of the pressure part of the piston serves as a support for the switchable cam follower and projects axially beyond a housing edge, in which in the end face of the head of the piston an opening for flowing through a hydraulic means for applying a hydraulically controllable coupling device in the switchable Trailing lever is formed, wherein the housing has a first radial passage and axially spaced therefrom a second radial passage for hydraulic means, and in which on the support member is formed a hydraulic lash adjuster for the finger follower, said

- the sleeve has a first and a second hollow cylindrical portion, each having a different diameter and connected by an offset portion and spaced from each other.
- this support element may be provided that the first portion of the sleeve rests hydraulically close to a radial inner surface of the pressure part of the piston, and that between the second portion of the sleeve and an axial portion of the inner surface of the pressure part of the piston, an annular space is formed.
- a mechanically fixed and hydraulically sealingly closing seat of the sleeve is achieved in the head part of the piston, wherein at the same time a hydraulic connection between the second radial passage opening in the piston and the axial opening in the head of the pressure part of the piston is created.

- the first passage in the housing and the radial passage opening in the working part of the piston and the second passage in the housing and the radial passage opening in the pressure part of the piston are arranged axially offset from each other without axial overlap. As a result, the flow velocity of the hydraulic fluid can be reduced.
- a locking ring is arranged between a shoulder formed on the bore of the housing and a shoulder formed on the outer surface of the pressure part.
- a shoulder formed on the bore of the housing is arranged between a shoulder formed on the bore of the housing and a shoulder formed on the outer surface of the pressure part.
