Abstract
The utility model discloses an engine hydraulic tappet, which comprises a tappet piston (1) and a turning adjusting device (2) positioned below the tappet piston, wherein, the tappet piston (1) and the turning adjusting device (2) can do relative rotation; the tappet can keep a rotation with a certain angle with an air valve (4) through the relative rotation between the tappet piston (1) and the turning adjusting device (2); and one end of the bottom connected with the air valve (4) of the turning adjusting device (2) is provided with a groove (3), and the groove (3) can be directly sleeved on the top end of the air valve (4) to prevent the air valve (4) from shifting excursion during the movement process. The engine hydraulic tappet having the special structure makes an engine be more flexible during layout process, the engine can be directly driven by a cam, the tappet and a swinging arm can be made into a whole body, and the engine can be combined with an air valve bridge to satisfy different layout needs. A unique air valve turning device can prevent the air valve from shifting excursion during the movement process.
Description
Technical field
The utility model relates to a kind of motor hydraulic pressure tappet.
Background technique
General motor hydraulic pressure tappet is divided into plunger and tappet shell two-part, tappet need consider that when arranging tappet and valve must keep the two center line all the time point-blank in movement process, otherwise it is arranged apart that the two needs, and engine arrangement is had relatively high expectations; Yet with valve and the tappet lost motion that also increases each component arranged apart, the validity that the valve clearance is adjusted reduces, and valve directly contacts with tappet, the no any guiding device in centre, and valve is offset easily.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of motor hydraulic pressure tappet at problems of the prior art, its objective is that anti-air-stop gate is offset in movement process.
The technical solution of the utility model be this a kind of motor hydraulic pressure tappet comprise plunger and be positioned at its below turn to regulating device, an end that turns to the bottom of regulating device to be connected with valve is provided with the valve guiding device.
Described plunger with turn between the regulating device and can rotate relatively.
Described valve guiding device is to be provided with groove in the bottom that turns to regulating device.
A kind of motor hydraulic pressure tappet with above-mentioned special construction has the following advantages:
1, since plunger with turn between the regulating device and can rotate relatively, therefore, when tappet is connected with valve, valve also can rotate with respect to tappet, make motor more flexible in placement process, can directly use cam drive, also tappet and rocking arm can be made of one formula, can also combine with air valve bridge, satisfy different layout needs.
2, Du Te valve guiding device can prevent that air-stop gate produces skew in movement process.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model and rocking arm are made of one.
Fig. 3 is the structural representation that the utility model and air valve bridge are made of one.
In Fig. 1-3,1: plunger; 2: turn to regulating device; 3: groove; 4: valve; 5: the rocking arm roller; 6: cam; 7: air valve bridge.
Embodiment
Figure 1 shows that the structural representation of the utility model motor hydraulic pressure tappet.By as can be known shown in Figure 1, what this a kind of motor hydraulic pressure tappet comprised plunger 1 and was positioned at its below turns to regulating device 2, plunger 1 with turn between the regulating device 2 and can rotate relatively, tappet is in the course of the work by plunger 1 with turn to the relative rotation between the regulating device 2 to keep forwarding to of several angles with valve 4; An end that turns to the bottom of regulating device 2 to be connected with valve 4 is provided with groove 3, and groove 3 can directly be enclosed within the top of valve 4, and anti-air-stop gate 4 is offset in movement process.
Fig. 2 is the structural representation that the utility model and rocking arm are made of one, and Fig. 3 is the structural representation that the utility model and air valve bridge 7 are made of one.By Fig. 2 and Fig. 3 in conjunction with as can be known, because the terminal place that is connected with valve 4 of tappet can be rotated, so can directly drive with cam 6, also tappet and rocking arm can be made of one formula, can also combine with air valve bridge 7, satisfy different layout needs, unique valve guiding device can prevent that air-stop gate 4 is offset in movement process.
Concrete working procedure is: when cam 6 basic circles contact with rocking arm roller 5, valve 4 is closed, this moment rocking arm tappet end turn to regulating device 2 and tappet end central lines (also with valve 4 central lines), in cam 6 rotation processes, when peach tip contacts with rocking arm roller 5, valve 4 is opened, and this moment, the turning to and between regulating device 2 and the tappet end center line certain angle is arranged but still keep and the valve central lines of rocking arm tappet end realized turning to regulating action with this.
The tappet end installs this device additional, can be preferably the driving force of camshaft be delivered to valve 4 by hydraulic tappet, the moving direction of valve 4 all can remain unchanged in the whole process, simultaneously, groove 3 can directly be enclosed within valve 4 tops, and anti-air-stop gate 4 is offset in movement process.
This tappet and rocking arm are made of one, and have saved the arrangement space of a part, make to arrange more compactly, and this tappet and air valve bridge 7 are made of one, can more accurate adjusting valve clearance, and two parts are combined into a part, and saved a part of material, reduced cost.This hydraulic tappet also can drive with cam 6 separately simultaneously.
