Abstract

The invention provides a mechanical supercharger, which is a supercharger structure for enhancing the output pressure depending on the single actuating pressure of a spring; the problem that the original supercharger is limited in use because of dimensions can be solved. The mechanical supercharger is composed of a large cylinder body, a small cylinder body, a sealing element, a large piston, a small piston, a disc spring, an end cap and seal rings; the small piston is arranged in the through hole of the large cylinder body and the seal ring is arranged at the position where the small piston is contacted with the through hole, the small cylinder body is nested on the small piston, the seal ring is arranged at the position where the small piston and the large cylinder body are contacted, the sealing element is arranged in the groove of the sealing element of the large piston, the large piston is nested on the small piston, the seal ring is arranged at the position where the large piston is contacted with the small piston, the disc spring is nested on the large piston, and the end cap is arranged at the opening end of the large cylinder body. The mechanical supercharger has the advantage of compact the structure, thus the mechanical supercharger can be used at the position where the dimensions are required.

Description

Mechanical supercharger

Technical field: the invention is a kind of supercharger structure that improves delivery pressure by spring single-acting pressure.

Background technique: at present, the finished product supercharging device is restricted because of specification in the use as gas-liquid pressure-boosting device, gas gas pressurized machine, liquid liquid pressurized machine, can not satisfy the place that physical dimension is had requirement, therefore can not be applied widely.

Summary of the invention: the purpose of the invention provides a kind of compact structure, is fit to physical dimension is had the mechanical supercharger in the place of requirement; The purpose of the invention is to realize by following technological scheme: mechanical supercharger, it is characterized in that by big cylinder body, little cylinder body, seal element, big piston, small piston, belleville spring, end cap, seal ring constitutes, big cylinder body one end is made opening shape bottom portion and is made through hole, on sidewall, make inlet hole, exhaust port, make through hole and vent on the little cylinder body, the big piston external diameter is made step-like, and making the seal element groove with big cylinder body contacting point, make on the big piston small piston through hole is installed, make inward recess and through hole on the end cap, make vent on the small piston; Small piston is installed in the through hole of big cylinder body and seal ring is installed at small piston and through hole contacting point, little cylinder body is sleeved on the small piston, with small piston, big cylinder body contacting point seal ring is being installed, Sealing is installed in the seal element groove of big piston, big piston is sleeved on the small piston, seal ring is installed, belleville spring is sleeved on the big piston with the small piston contacting point, end cap is installed in big cylinder body opening end, seal ring is installed on the external end face of vat.

The advantage of the invention: mechanical supercharger inner structural members compactness, the vat body diameter can use in the place that size requirement is arranged according to the environment size design.

Description of drawings:

Fig. 1 is the mechanical supercharger structure schematic representation.

Among the figure: 1. seal ring 2. big cylinder body 3. little cylinder body 4. seal elements 5. big pistons 6. small pistons 7. belleville springs 8. end caps 9. exhaust ports 10. inlet holes

Embodiment: mechanical supercharger, constitute by big cylinder body, little cylinder body, seal element, big piston, small piston, belleville spring, end cap, seal ring, big cylinder body one end is made the opening shape, bottom portion makes through hole, on sidewall, make inlet hole exhaust port, make through hole and vent on the little cylinder body, the big piston external diameter is made step-like, and making the seal element groove with big cylinder body contacting point, make on the big piston small piston through hole is installed, make inward recess and through hole on the end cap, make vent on the small piston; Small piston is installed in the through hole of big cylinder body and seal ring is installed at small piston and through hole contacting point, little cylinder body is sleeved on the small piston, with small piston, seal ring is installed in big cylinder body contacting point, seal element is installed in the seal element groove of big piston, big piston is sleeved on the small piston, with the small piston contacting point seal ring is installed, belleville spring is sleeved on the big piston, end cap is installed in big cylinder body opening end, leave the gap between big piston and the end cap termination, leave the gap between big piston and the little cylinder body exterior edge face, be used to charge into pressurized air, increase the pressure active area, leave the gap between small piston and the little cylinder body inner via hole, be used to store the hydraulic oil that discharges oil pressure, seal ring is installed on the external end face of vat.

Mechanical supercharger, when needing supercharging, belleville spring acts on the big piston in the mechanical supercharger, and spring pressure forces large and small piston to move to the left end limit position, gets high-pressure and hydraulic oil, at this moment plays pressurization; When the needs release pressure, in big cylinder body, feeding pressurized air, pressurized air acts on the large and small piston simultaneously, and big piston acts on the belleville spring, makes the belleville spring compression, the small piston release high pressure oil that moves right.
