Specific embodiment

Understand for the ease of those of ordinary skill in the art and implement the present invention, with reference to the accompanying drawing and specific embodiment The present invention is described in further detail.

It is piston 10, oil inlet pipe 2, fuel-displaced as shown in Figure 1, a kind of I.C Engine Laboratory lubricator, including lubricator cylinder body 4 Pipe 9, connector sleeve 3 and pedestal 15, piston 10 and 4 inner wall of lubricator cylinder body are fitted close, and are connected to by screw rod 7 with handle 6 One, oil inlet pipe 2 and flowline 9 are connected with lubricator cylinder body 4, and 4 bottom of lubricator cylinder body is connect with connector sleeve 3, connector sleeve 3 It is embedded on pedestal 15；

It is characterized by: being equipped with device in one-way on state, only import but no export between oil inlet pipe 2 and lubricator cylinder body 4；Flowline 9 Isolator 12, only export but no import are equipped between lubricator cylinder body 4.

As shown in figure 3, the device in one-way on state is steel ball B14, steel ball B14 is located in lubricator cylinder body 4 and oil inlet pipe 2 Be connected place, and diameter is greater than oil inlet；

When lubricator piston 10 moves upwards, 4 Internal steel ball B14 of lubricator cylinder body is inhaled into inside cylinder body 4, oil plant quilt It sucks inside lubricator cylinder body 4；When piston 10 moves downward, 4 Internal steel ball B14 of lubricator cylinder body is blocked up due to gravity Hydraulic fluid port is lived in, oil inlet pipe 2 is sealed, oil plant cannot be flowed out through oil inlet pipe 2.
