Abstract
The utility model relates to a new platy valve sheet cylinder head structure of an air compressor, and belongs to the technical field of an air compressor. The utility model is characterized in that a cylinder head part is divided into a cylinder head cover and a valve seat plate, and air inlet valves and exhaust valves are mainly arranged on the valve seat plate. In this way, the utility model uses less parts to complete the main air inlet and exhaust functions, and causes the air inlet and exhaust resistance to be reduced. The utility model has the advantages of simple structure, good reliability and good performance, improves the charging efficiency, and is an ideal structure of a platy valve sheet cylinder head of a vehicle air compressor.
Description
The utility model relates to the tabular valve block cylinder cap of a kind of air compressor new structure.
General tabular valve and the Reed Valve two big classes of dividing of present automobile-used air compressor cylinder cap spare, tabular valve arrangement generally is made up of part more than 12 kinds, as valve seat and the related part spring that brought for valve seat installing and fixing on cylinder cap etc., there are four or five kinds for the installation of valve seat on cylinder cap with fixing used related part like this, make it bring complex structure, disadvantage such as poor reliability such as air inlet are pressed female loosening, and intake and exhaust are not smooth, air compressor is not inflated, and inflating often all is to be caused by the unreliable institute of these parts slowly.
The purpose of this utility model is that simplified structure raising reliability concrete grammar is the cylinder cap separated into two parts, and a part is a cylinder head cover, and a part is a seat board, like this, valve seat is fabricated directly on the plate, makes a lot of related part above-mentioned go to disappear, thereby simplifies the structure.
Feature of the present utility model is: pressing plate (6), inlet valve spring (5), the valve block (4) of induction part directly are combined on the seat board (7), the discharge portion valve block is installed on the seat board, and edge cover (2) exhaust return spring (3) is fitted in the exhaust cavity on the cylinder head cover (1).
Accompanying drawing is cylinder cap new structure figure.
1. cylinder head covers, 2. edge covers, 3. exhaust return springs, 4. valve blocks, 5. air inlet springs, 6. pressing plates, 7. seat boards, 8. gland shims among the figure
The utility model is to realize like this, its structure is by cylinder head cover (1), edge cover (2), exhaust return spring (3), valve block (4), inlet valve spring (5), pressing plate (6), seat board (7), gland shim (8) is formed, air is sucked by the A hole during air compressor air intake, air-intake valve plate (4) is opened, enter piston head, effect owing to pressure reduction and air inlet spring when piston stroking upward carries out exhaust stroke makes air-intake valve plate move and lean against on the pressing plate in time, realize sealing, and at this moment exhaust valve plate is opened, compression exhaust return spring and be limiter with edge cover, pressurized air is discharged through the B hole, the exhaust valve plate sealed mouth is arranged on the seat board, and the suction valve sealed mouth is located on the pressing plate (6).
The sealing of cylinder head cover and seat board is finished by cylinder cover cushion (8), and their connection is finished when connecting with cylinder sleeve by cylinder bolt.
The utility model is compared with original technology, have simple in structure, cost is low, reliability is high, efficient is high Characteristics, can be widely used on the various vehicle air compressors.
