Consider that charge oil pressure is very high in the fuel pipe 5, the most important thing is that before 5 pairs of adaptor unions 20 of oil pipe were fastened,

adaptor union

19 and 20 can not be thrown off mutually.Fig. 4-7 expression pipe coupling comprises the shut off valve 35 of an

adaptor union

19,20 and a fuel line 5, latter's adjacent tube joint 20.Valve and pipe coupling are combined into: can not spill oil to ambient atmosphere through adaptor union 20 from fuel pipe 5.Fig. 4 and Fig. 5 represent that adaptor union 20 passes through spherical shut off valve 35 and links fuel pipe 5, by arm 37 spherical valve are moved between the opening and closing position, and arm 37 can rotate around axle 36, and the face cam 38 with cam rail 39 is secured on the arm 37.In the closed position at the spherical valve 35 shown in Fig. 4 and Fig. 5, this moment, arm 37 was upright.Swivel arm 37 makes face cam 38 cws among Fig. 4 turn over 90 °, and valve 35 moves to open position.

Plate 40 is fixed on the valve 35 and is in the back of face cam 38, extends upward along adaptor union 20.In the vertical slot 42 of

bolt

43 and 44 with bar 41 load plates 40, bolt 44 passes the guide groove 39 of face cam 38.

The distance of the relative axle of the main extendible portion on the guide groove 39 36 line of centerss is constant, but guide groove one end has the distance minimizing of individual position 45 with respect to axle 36 line of centerss.Because such design guide groove 39, when arm when the position of opening ball valve 35 forwards its off position to, bar 41 is in upper position, continue subsequently at equidirectional swivel arm 37, by with position 45 concerted actions, bolt 44 is just drawn towards axle 36 directions, bar 41 is also like this.Like this, during the decline action of arm 37 towards the open position that leaves valve to its off position, bar 41 carries out vertical translation.This motion of translation of bar 41 is used for making the pipe coupling that comprises
