Description

8306150-7 l0 l5 20 30 35 Cylindergaveln 12 är försedd med en hals 20 som är utformad med en med kolvstången 15 koaxiell cirkulärcylindrisk ytteryta 50. En första justerhylsa 51 är roterbart lagrad på denna cylindriska yta 50 och uppvisar ett rörformigt nackparti 52 vilket är utformat med en central öppning 53. Tvärsnittet hos öppningen 53 har en form som kongruent motsvarar kolvstångens 15. dusterhylsan 51 är försedd med ett axiellt spår 55 samt en tvärgående klämskruv 56 genom vilken hylsan 51 kan låsas relativt halsen 20. Nackpartiet 52 uppvisar en yttre cylindrisk yta 57 vilken uppbär en roterbar andra justerhylsa 60. Hylsan 60 är också försedd med ett axiellt spår 61 ochen tvärgående klämskruv 62 för låsning av hylsan 60 relativt nackpartiet 52. På samma sätt som justerhylsan 51 är hylsan 60 försedd med ett nackparti 63 innefattande en central öppning 64 med en tvärsnittsform motsvarande kolvstångens 15. The cylinder head 12 is provided with a neck 20 which is formed with a circular-cylindrical outer surface 50 coaxial with the piston rod 15. A first adjusting sleeve 51 is rotatably mounted on this cylindrical surface 50 and has a tubular neck portion 52 which is formed with a central opening 53. The cross section of the opening 53 has a shape which congruently corresponds to the duster sleeve 51 of the piston rod 15. is provided with an axial groove 55 and a transverse clamping screw 56 through which the sleeve 51 can be locked relative to the neck 20. The neck portion 52 has an outer cylindrical surface 57 which carries a rotatable second adjusting sleeve 60. The sleeve 60 is also provided with an axial groove 61 and a transverse clamping screw 62 for locking the sleeve 60 relative to the neck portion 52. In the same way as the adjusting sleeve 51, the sleeve 60 is provided with a neck portion 63 comprising a central opening 64 with a cross-sectional shape corresponding to the piston rod 15.

Inställning av det radiella och tangentiella spelet hos kolvstången 15 relativt cyindergaveln 12 åstadkommes genom vridinställning av justerhylsorna 51 och 60 relativt varandra och relativt gaveln 12.Adjustment of the radial and tangential play of the piston rod 15 relative to the cylinder end 12 is accomplished by rotationally adjusting the adjusting sleeves 51 and 60 relative to each other and relative to the end 12.

För att minimera risken för fastlåsning av kolvstången 15 bör hylsan 60 hållas i linje med cylindergavelöppningen 22 under det att hylsan 51 vrides för att uppnå ett önskat spel mot kolvstången 15. Då det önskade spelet uppnåtts låses hylsorna 51 och 60 reltivt varandra och relativt gaveln 12 genom klämskruvarna 56 och 62. Beroende på kolvstångens icke-cirkulära tvärsnittsform åstadkommes på detta sätt en justering både av det tangentiella spelet och det radiella spelet mellan kolvstången 15 och cylindergaveln 12.To minimize the risk of locking the piston rod 15, the sleeve 60 should be kept in line with the cylinder end opening 22 while the sleeve 51 is rotated to achieve a desired play against the piston rod 15. When the desired play is achieved, the sleeves 51 and 60 are locked relative to each other and relative to the end 12 through the clamping screws 56 and 62. Depending on the non-circular cross-sectional shape of the piston rod, an adjustment of both the tangential play and the radial play between the piston rod 15 and the cylinder head 12 is achieved in this way.

Det bör påpekas att uppfinningen icke är begränsad till den trekantiga liktjockingprofilen utan omfattar alla andra icke-cirkulära runda tvärsektiner vilka medger rotationslåsning av kolvstången liksom användning av elastiska tätningar av standardtyp.It should be noted that the invention is not limited to the triangular corrugated profile but includes all other non-circular round cross-sections which allow rotational locking of the piston rod as well as the use of standard elastic seals.

Icke heller är uppfinningen begränsad till arrangemanget med tvâ justerhylsor. En enda vridbar justerhylsa ger tillsammans med cylindergavelöppningen samma möjligheter till speljustering såsom avses med uppfinningen.Nor is the invention limited to the arrangement with two adjusting sleeves. A single rotatable adjusting sleeve together with the cylinder end opening provides the same possibilities for game adjustment as intended by the invention.
