Abstract
The utility model relates to an universal fittings for petrol machine, in particular to a starting and pressure relief apparatus for petrol machine, which comprises a camshaft 1, an eccentric arm 2 and a reset spring between the camshaft and the eccentric arm, which is characterized in that: a pressure reducing block 4 is vertical to the eccentric arm, and the pressure reducing block is corresponding to the position of cam base circle 5. The utility model has the advantages of less part, simple structure, simple technical for assembling, etc.
Description
One, technical field
The utility model relates to a kind of general gasoline engines accessory, and particularly general gasoline engines starts the release device.
Two, background technique
Generally before startup, its valve is to be in open mode to general gasoline engines, and behind gasoline engine starting, its valve need be closed storage and be pressed.It started rotating shaft and the shift fork of rotational fixation on the camshaft basic circle that pressure relief device includes centrifuge arm, Returnning spring, rotational fixation centrifuge arm in the past, it is centrifuge arm to be rotated around the axis drive shift fork to rotate by centrifugal force to make valve-closing, its deficiency is that its centrifuge arm and shift fork are separated into two parts, and the axle around oneself rotates separately, and structure is complicated, part is many, assembly technology is complicated.
Three, technology contents
The purpose of this utility model be exactly design a kind of simple in structure, part is few, the general gasoline engines of easy assembling starts the release cam.It includes camshaft, centrifuge arm and Returnning spring between the two, it is characterized in that: a decompression piece is vertically arranged on centrifuge arm, and the decompression piece is corresponding to the cam base circle position.
The utility model is behind gasoline engine starting, because the rotation of camshaft, centrifuge arm is under action of centrifugal force, and the pulling force that overcomes resetting means outwards moves, and the decompression piece on the centrifuge arm moves with centrifuge arm in the circumference of returning cam base circle, valve-closing; When the rotation of camshaft was lower than certain rotating speed, the pulling force of resetting means resetted centrifuge arm, and the decompression piece protrudes from the camshaft basic circle thereupon valve is backed down, and made the flame-out shutdown of petrol engine.Advantages such as the utility model has been owing to reduced the bearing pin etc. of shift fork and rotational fixation shift fork, and it is less, simple in structure therefore to have a part, and assembly technology is simple.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to side view;
Fig. 3 is Figure 1A portion partial enlarged drawing.
Among the figure: 1-camshaft 2-centrifuge arm 3-Returnning spring 4-decompression piece 5-cam base circle 6-directional post 7-guide chute I 8-guide chute II 9-self-locking chute 10-decompression piece cambered surface 11-balancing weight
Five, embodiment
Below in conjunction with accompanying drawing and enforcement example the utility model is further described:
As shown in Figure 1, model utility includes camshaft 1, centrifuge arm 2 and resetting means between the two.It is characterized in that: a decompression piece 4 is vertically arranged on centrifuge arm 2, and decompression piece 4 is corresponding to cam base circle 5 positions.When camshaft 1 was in halted state, because the effect of self-locking chute 9 makes centrifuge arm 2 remain on the home position, decompression piece 4 protruded from cam base circle 5, and valve is in the state of backing down, thereby plays the purpose of release when starting.In the start-up course of petrol engine, when camshaft 1 rotating speed reaches the technical requirements value,, under the control of directional post 6 and two guide chutes 7, produce displacement along certain movement locus because action of centrifugal force makes centrifuge arm 2 overcome the pulling force of resetting means.Decompression piece 4 on the centrifuge arm 2 also moves thereupon, returns in the circumference of cam base circle 5, and valve-closing, as shown in Figure 2.Make motion that valve gives by cam curve and proper functioning.Centrifuge arm 2 is provided with the two combined guided chute 8 that cooperates with directional post 6 on the camshaft 1, and is more stable, more reasonable with the movement locus of guaranteeing centrifuge arm 2; Decompression piece 4 outers can be the cambered surface corresponding with the circumference of cam base circle 5, as shown in Figure 3, and with this purpose that reaches release and close valve.Can be furnished with balancing weight 11 on the centrifuge arm, guarantee that pressure relief device can proper functioning under the rotating speed of technical requirements.
Claims (6)
1, a kind of general gasoline engines cam includes camshaft (1), centrifuge arm (2) and resetting means between the two (3), it is characterized in that: a decompression piece (4) is vertically arranged on centrifuge arm, and the decompression piece is corresponding to the position of cam base circle (5).
2, as claims 1 described general gasoline engines cam, it is characterized in that: the guide chute that cooperates with directional post (6) on the camshaft is arranged on the centrifuge arm.
3, require 2 described general gasoline engines cams as profit, it is characterized in that: the chute that cooperates with the camshaft directional post on the centrifuge arm is the two guide chutes (7) (8) of combined type.
4, general gasoline engines cam as claimed in claim 3 is characterized in that: at guide chute (8) rear portion self-locking chute (9) is arranged.
5, general gasoline engines cam as claimed in claim 1 is characterized in that: decompression piece outer is the cambered surface (10) corresponding with the circumference of cam base circle.
6, general gasoline engines cam as claimed in claim 1 is characterized in that: balancing weight (11) is arranged on the centrifuge arm.
