iracnrnn IPEUVKDJED WITH VALVES.
Application filed January 10, 119811. Serial No. 486.27%.
To all whom it may concern:
Be it known that l, Mano Bmmo'r, citizen of the Republic of Switzerland, residing at Boisfiolombcs, Department of Some, France, have invented certa n new and useful Improvements in Machines lrov ded with Valves, of which the followmg 1s a specification. I
The invention relates to machines provided with'valves and more particularly,
but not exclusively, to internal combustion engines especially of the multi-cylinder type, by reason of the great advantages to be obtained in connection with such engines.
The principal object of-the invention 18 to afi'ord a method for the arrangement of engine valve systems which shall provide a more simple construction, as well as an exact assemblage and a more ready do mounting of the same.
The invention is aplicable to the already-known removale valve guiding members of such machines, and itconsists mainly in a suitable arrangement of the said valve guides and of the recess into which these are fitted axially upon the en gine; these valve guides, when assembled upon the engine together with their corresponding valves and the annexed parts of the latter, are suitably disposed to receive the action of an elastic means comprised between the said annexed parts; the elastic means tending to maintain the valve guides in close fitting connection with their said recesses.
Aside from this principal disposition, the invention relates to certain other arrange ments which are preferably employed in conjunction with the foregoing, and which will be further set iorth.
The invention relates more especially to certainmethods of application and construction of the said arrangements.
The invention is clearly set forth in the accompanying description and drawing, both oi. which are given by way of example.
The drawing represents a partial section through the axis of one of the valves of an internal combustion engine. oil the valveoperated type constructed according to the invention,
In the present method, and more particularly according to a preferred embodiment of the same, let it be supposed that, whilst constructing a multi-cylinder, it it is pro-=- posed to construct the parts containing the valves, as well as the valves themselves, the following or similar method will be adopted.
Each of the guide pieces a of the valves is constructed, at least as concerns its lower part, of conical shape and preferably at a very acute angle. Suitable means are provided for securing the pressure p of the springs c upon the guide piece, either directly or through the medium of a small circular disc 6, these springs being employed to hold the valve upon its seat. in the case where the circular disc is used, the said means can be provided in the shape of a simple shoulder a upon the said valve guide iece.
Eac of the respective parts 03 of the engine which are employed to contain the valves is constructed, in order to receive these valve guides, with a bored out ortion having a conical shape correspon ing to that of the valve guide a, and-also con-' tains a valve seat 03 for the use of the said valve. The construction of the valves themselves is as follows. The valve stem 0 is arranged to slide within its uide piece a, the stem being adjustable in ength and adapted to receive the action of the said springs as well as of the cam f. To this ell'ect, the upper part of the valve is constructed on the already known method consisting in the use of a disc 9 provided with a rod 9 which is suitably threaded to screw adjustably with a corresponding thread disposed in the said valve stem e a circular cap it is arranged so that it can be mounted between this disc and the spring orsprings c; the cap it is provided with a small stud or projection which engages within a corresponding recess on the upper end of the valve stem 6 and it also com prises a toothed portion k adapted to engage with a corresponding toothed portion g of the disc 9 when under the action of the springs c. l deans are also provided on one hand of the cap it and on the other hand of the disc g, in order to cause the rotation of the'disc g with reference to the valve proper, by the use of a key or wrench (not shown here) applied upon the said means 9, this operation being performed in spite of the presence of the locking de= vice formed by the said sets of teeth, and thus permitting the lengthwise adjustment of the said valve stem.
By the above method, an engine can be lltl devised which possesses a high relative economy in the construction of the valve guides and also the members which contain these guides, and also affords the following advantages in addition to the diminished cost of construction; the valve guides can be properly mounted with much greater facility; the valve guides are made interchangeable by a much more advantageous constructional method; all wear of parts is suppressed during the demounting and assembling of the said valve guides; leakage at the joints between the Valve guides and the sockets into which they are fitted is reduced to a considerable degree.
It is of course understood, as has in fact been implied, that the scope of the invention is not limited to any one of the methods of application or construction which shall have been more particularly set forth, but on the contrary it comprises all alternate forms within the scope of the claims.
1. In a machine, such as an internal combustion engine havlng a removable frustomaintain the valve guide in close fitting connection with its recess.
2. In a machine, such as an internal combustion engine, a shouldered valve guide the lower part of which is of frusto-conical shape axially fitted in a corresponding frusto-conical recess of the engine, a valve the stem of which is guided in the said valve guide member, a disc fixed on the end of the stem opposite to the valve, and elastic means interposed between the shoulder of the valve guide and the said disc, whereby the valve is maintained normally closed and the valve guide is held snugly fitting in the recess.
In testimony whereof I have hereunto set my hand.
