The operation process of multiple compressor of the present invention is described below with reference to Fig. 6.
Fig. 6 a shows that piston 55 that the piston 55 of the 1st cylinder 50 is positioned at top dead center and the 2nd cylinder 50 ' is positioned at the state of lower dead center.Above-mentioned the 1st cylinder 50 is states of having arranged compression working fluid, and the 2nd cylinder 50 ' is to suck the state of wanting compression working fluid.
In this state, bent axle 30 is that benchmark rotates to clockwise direction with the drawing, then becomes the state of Fig. 6 b.That is, suck the stroke of wanting compression working fluid, carry out the working fluid compression stroke at the 2nd cylinder 50 ' at the 1st cylinder 50.
At this moment, connecting rod 60,60 ' and cam pin 32 between the active force relation as follows.Owing to carry out suction stroke at the 1st cylinder 50, cam pin 32 applies the active force of pulling connecting rod 60 ' direction to connecting rod 60 '.Thus, pin connects the sidewall that pommel breakthrough part 43 is close in pommel 62.
In addition, in the 2nd cylinder 50 ' one side, cam pin 32 applies the active force that promotes connecting rod 60 directions to connecting rod 60.Thus, pin connects pommel 62 and is close to pommel mounting groove 33.
If bent axle 30 continues rotation, shown in Fig. 6 c, piston 55 is positioned at lower dead center, and cylinder 50 enters the state of wanting the compression working fluid suction stroke to finish.And, in cylinder 50 ',, piston 55 enters the state of having arranged compression working fluid because of being positioned at top dead center.
In Fig. 6 d, above-mentioned bent axle 30 continues rotation, so proceed the compression stroke of pressing chamber 51 internal work fluids in cylinder 50, sucks the stroke of wanting compression working fluid in the 2nd cylinder 50 '.At this moment, the active force between cam pin 32 and the connecting rod 60,60 ' is just in time opposite with what illustrate among Fig. 6 b.Illustrated process is carried out repeatedly among above-mentioned Fig. 6.
In above-mentioned operation process,, connect cover 40 with cam pin 32 certain circular trace of drawing together according to the rotation of bent axle 30.That is the circular trace revolution of cam pin 32, to draw.
In addition, under the situations that connection cover 40 is not connected and fixed with a side connecting rod 60 ', it may be the center rotation with cam pin 32 that connection covers 40.Above-mentioned rotation is to have certain clearance because rotate glibly between cam pin 32, pin connection pommel 62 and the connection cover 40, so cause by above-mentioned slit.But, if connect cover 40 rotations, connect pommel 62 with pin and conflict mutually, may produce running noise thus.
Above-mentioned running noise may produce under the situation of Fig. 6 b and Fig. 6 d, but among the present invention owing to connect cover 40 and connecting rod 60 ' welding is fixing, so can prevent to produce running noise.That is, under the situations that connection cover 40 is connected and fixed with a side connecting rod 60 ', can prevent to connect cover 40 rotations in operation process.Thus, connect the phenomenon that can not clash between cover 40 and the pin connection pommel 62, can prevent to produce running noise.
And, among the present invention cam pin 32, connect cover 40 and connecting rod 60,60 ' combining structure is designed to make the slide part between them to minimize, the loss of reducing friction.That is, pin connects pommel 62 and contacts with 33 of the pommel mounting grooves of cam pin 32, and also is that narrow relatively face contacts with the pommel breakthrough part 43 inner faces contact that connects cover 40, therefore, the power loss that is caused by friction between them is minimized.
