Abstract
A pressing-in type oil passage check valve for an engine is characterized in that the check valve comprises a spring, a steel ball, a plug and a housing, wherein the steel ball and the spring are installed in the housing in sequence, then the plug is pressed in. The check valve has the advantages of simple structure, low cost, high reliability, convenient installation, good reliability and fast response, etc.
Description
Technical field
The utility model belongs to the technical field that motor is made, and particularly motor is with forced oil duct safety check.
Background technique
At present; the application of quiet catenary system in motor increases gradually; because the special construction of V-type engine; upper left-hand stretcher fuel supply chamber often is higher than fuel feeding oil duct inlet; cause the machine oil behind the engine shutdown to flow backwards; can't realize the lasting fuel feeding of stretcher, this will cause the engine start noise big, and influences the chain life-span.
Summary of the invention
The utility model purpose provides a kind of motor with forced oil duct safety check.
The technical solution of the utility model is achieved in that
Motor is with forced oil duct safety check, and it is characterized by: it is made up of spring, steel ball, obstruction and shell, with steel ball, the spring shell of successively packing into, is pressed into obstruction then.
The utlity model has simple in structure, with low cost, characteristics such as reliability is high, easy for installation, good reliability, response are rapid.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The structural representation that Fig. 2 stops up for the utility model.
Fig. 3 is the utility model working state schematic representation.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Motor is characterized by with forced oil duct safety check: it by spring 3, steel ball 2, stop up 4 and shell 1 forms, with steel ball 2, spring 3 shell 1 of successively packing into, be pressed into obstruction 4 then.
Embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, because the chain tensioning device oil duct diameter on the cylinder cap is less, therefore cooperates between safety check of the present utility model and the cylinder cap and adopt forced structure rather than worm structure, have enough thickness with assurance safety check shell 1, to guarantee enough rigidity and intensity.
When normal working of engine, cause that for preventing that the oil duct internal pressure is too high spring 3 kills doubling-up and influences flow, in obstruction 4, open six semi-circular hole, 5 earial drainage dependable flows.
For guaranteeing reliability of products, adopted spring 3 and steel ball 2 structure control valve bodies to open and close.After engine oil pressure was set up, steel ball 2 was subjected to engine oil pressure effect pressure spring 3, and machine oil flows through safety check from the steel ball 2 and the gap of shell 1; Behind tail-off, steel ball 2 is subjected to spring 3 pretightening force effects, is pressed on the conical surface of diagram shell 1 housing, forms reliable sealing.
Claims (2)
1. motor is characterized by with forced oil duct safety check: it by spring (3), steel ball (2), stop up (4) and shell (1) is formed, with steel ball (2), spring (3) the priority shell (1) of packing into, be pressed into obstruction (4) then.
2. motor according to claim 1 is characterized by: open six semi-circular hole (5) in the described obstruction (4) with forced oil duct safety check.
