Piston Compressor
Axial piston refrigerant compressor with piston front face projection
An axial piston refrigerant mini compressor according to flollowing, wherein a cross-sectional area defined by the outlet opening decreases in the direction of an outside surface of the valve plate, the cross-sectional area defined by the projection decreases towards a free end and that the cross-sectional areas of the outlet opening and the projection change in the axial direction in such a way that during the piston movement towards the upper dead center the free cross-sectional area of the flow channel changes at a rate that is less than a rate of change in the volume remaining in the pressure chamber of the cylinder.
In particular, the mini compressor according to the invention can be designed in such a way that the junction surface between the valve plate surface and the outlet opening and the junction surface between the piston front end and the projection have a continuous shape, the junction surface between the outlet opening and the valve seat and the junction surface between the projection and the piston front end being rounded. Thus, gas discharge during draining of the cylinder can take place almost without creating eddies, thus decreasing the flow resistance.
The invention relates to a refrigerant mini compressor comprising at least one piston-cylinder unit and one valve plate that has at least one outlet opening. The piston has a projection which projects into the outlet opening when the piston is located near the upper dead center thereof. The aim of the invention is to increase the efficiency and to reduce the noise level. To these ends, the invention provides that the outlet opening, piston projection, valve plate and piston delimit a flow channel, and provides that the free cross-sectional area of the flow channel is determined by the smallest cross-sectional area of the outlet opening until the piston, during its pressure stroke at least the height (H) of the outlet opening, is located underneath the upper dead center.

why does an air compressor have a long piston?
because its longer compared to other kind of machines that has a piston.
what is the purpose of it because its piston is longer compared to other machines.
Its a big compressor.
