In brief, inhale -^compression-^work-^ exhaust.

So, there is provided a device using reciprocal movement of the piston to 20 transfer fluid. The working process of the device is that, the piston moves upward to create a negative pressure area in the receiving chamber, fluid is compressed into the receiving chamber through the input passage by the effect of the atmosphere. The downward movement of the piston within the receiving chamber compresses fluid therein out of the receiving 25 chamber through the output passage. 2/7 A single cycle of motion is separated into an input phase and an output phase. The receiving chamber communicates with the input passage during the input phase, the receiving chamber communicates with the output passage during the output phase. A cartridge freely hermetically rotating 5 inside the receiving chamber achieves the switching between the input phase and the output phase, it is a problem to achieve that the rotation of the cartridge interacts with the movement of the piston.

Summary of the present invention The object of the invention is to provide a triggering wheel for the fluid transfer device so as to solve the above problem.

A triggering wheel for the fluid transfer device comprises a disc-shaped fixed sheet with a transmission bore; the triggering wheel further comprises a is triggering block uniformly arranged in a ring array, the axis of the array is the axis of the fixed sheet, the triggering block is axially clamped between two fixed sheets, the triggering block is coaxially provided with an interior arcuate surface and an exterior arcuate surface, both the head side surface and the tail side surface of the triggering block tangentially connects with 20 the interior arcuate surface and the exterior arcuate surface through the arcuate surface, the interior and exterior arcuate surfaces are coaxial with the fixed sheet.

Preferably, the quantity of the triggering block is 2.

Specifically, the fixed sheet and the triggering block are fastened together by rivet. 3/7 Advantageous Effects The intermittent interaction between the triggering block and the triggering end achieves the interaction between the upward-and-downward 5 movement of the piston and the rotation of the cartridge.

Because the interior and exterior arcuate surfaces are coaxial, and the axises of the interior and exterior arcuate surfaces are coaxial with the axis of the fixed sheet, a tangent condition between the exterior arcuate surface and the triggering end will be achieved, such tangent condition makes the 10 cartridge retain at the present position, that is leaving the receiving chamber communicated with the input passage or the output passage.

Three of the four input passages 4 are sealed by plugs, and three of the four output passages 5 are sealed by plugs, the transfer device only keeps one input passage 4 and one output passage 5.

For better understanding the triggering wheel, one piece of fixed sheet 6 of io the triggering wheel in Fig.l is hidden, the triggering end 8 with a round tail end mates with the triggering block 7, the triggering end 8 is fixedly connected with the cartridge 3, the triggering end 8 is located between two fixed sheets 6 of the triggering wheel. The rotation of the crankshaft drives the piston 2 moving reciprocally in the receiving chamber 1, the crankshaft is transfers the power to the transmission shaft through the belt wheel, the transmission shaft drives the triggering wheel rotating through the transmission bore configured on the fixed sheet 6.

The triggering end 8 retains at the position shown in Fig.l under the elastic 20 force of the reset component, the end portion of the triggering end 8 is at the middle position between two triggering blocks 7, and the distance between the triggering end 8 and the triggering block 7 is equal. The first passage 9 of the cartridge 3 communicates with the receiving chamber 1, the second passage 10 of the cartridge 3 communicates with the output 25 passage 5, that is the receiving chamber 1 communicates with the output passage 5 with the help of the cartridge 3. /7 The triggering wheel rotates in a clockwise direction during the piston 2 moving downward, when the triggering wheel rotates a certain angle, the piston 2 is near to the constriction of the receiving chamber 1, the arcuate surface 13 of the head side surface of the triggering block 7 touches the end 5 portion of the triggering end 8, after this, the piston 2 goes on moving downward, meanwhile the triggering block 7 pushes the triggering end 8 to rotate, the cartridge 3 rotates as the triggering end 8 rotates, the second passage 10 and the output passage 5 are gradually staggered till the piston 2 moves downward to the extreme position, that is the bottom dead center, io the second passage 10 do not communicate with output passage 5 at all.
