Abstract
The invention relates to a kind of high-pressure oil pump of cylinder plug type that is designed to employ in supplying oil system of diesel engine of compress-burned type, which can supply constant high-pressure fuel for engine. There are two different features between the pump and the traditional pump. Firstly, every cylinder plug in traditional pump all stand side by side. Every more well knit and firm than the traditional ni structure. Secondary, traditional oil pump push cylinder plug works with cam shaft and yet the invention push down cylinder plug with cam tray which has several raised place. The cam stray is so simple and small that works stably. The design and principle of working in the invention steam from traditional oil pump. The main components, as cylinder plug, oil valve, oil clumber-controlled muff, are same with the traditional. But owing to the arranging of cylinder plug in different and the employing of cam tray, so to raise firm in structure, stable in working, meanwhile reducnig the weight of oil-pump.
Description
This design proposal can be used for the fuel oil supply system of diesel engine, and to change conventional oil pump flat structure, profile is a cylindrical body.
Be characterized in: each plunger (8) is the axle center annular array with transmission shaft (19), utilizes the rotation of cam disk (15) to oppress each plunger working in reciprocating mode.
This pump structure is as scheming: each parts of oil pump are installed on the pump housing (2), and the pump housing one side has detachable end (16), and most of parts are all put into installation from here, and plunger (8) number can be not wait more than 2.Cam disk closely is connected with transmission shaft, and fuel oil enters each plunger bushing through oil inlet pipe (12), when transmission shaft rotates, at first presses roller housing (14 include roller), promotes plunger simultaneously.Fuel oil backs down outlet valve (6) and extrudes from oil outlet tube (1), and oil outlet tube is fixing with screw (3), and seals with gasket seal (5) between the plunger bushing (7).Disappear when cam disk is rotated further pressure, roller housing and stake plug reset under the effect of compression spring (10) and spring (4), finish to press oil.Adjusting screw (13) is arranged at the roller housing bottom, can suitably regulate its front and back position.
Oil pump capacity is large and small to be finished by rotating fuel-flow control bar (20).The built-up gear (21) that the gear driven of one end is engaged with when rotating the fuel-flow control bar rotates, the plunger that rotates fuel control sleeve gear (9) at random and be attached thereto.Change the operating angle of plunger, promptly changed the size of oil pump capacity.
This oil pump is by lubricant oil joint (11) input lubricant oil.The oilhole (18) of lubricant oil through transmission shaft and cam disk inside enters between transmission shaft and the bearing shell (17), between cam disk and the roller housing, and the reciprocating gap location of roller housing, play the effect of lubricated each attrition surface.
This oil pump is compared with high pressure oil pump in the past, owing to adopt circular appearance, thereby more compact structure, firm, volume is littler, weight is lighter.Adopt cam disk to replace camshaft to finish oil pump work, thereby running is more steady rapidly.
Claims (1)
- " circular plunger type high pressure oil pump " is to use in the high pressure oil pump of diesel engine class compression ignition engine oil supply system.Its structure of more traditional oil pump is compact more, and in light weight, pressure is higher.It is characterized in that: each plunger is the axle center circular arrangement with the transmission shaft, utilizes the rotation compressing of cam disk to be equipped with the plunger working in reciprocating mode.
