A valve plate assembly for a compressor according to the principles of the present disclosure includes a valve plate and a suction valve retainer. The valve plate is configured to separate suction-pressure working fluid entering a cylinder of the compressor from discharge-pressure working fluid exiting the cylinder of the compressor. The valve plate defines a discharge valve seat. The suction valve retainer is configured to retain a suction valve within a suction valve seat disposed about a central longitudinal axis of the cylinder.

A gas transportation device is provided and includes a first flow guiding unit and a second flow guiding unit, each of which includes an inlet and an outlet. While the first flow guiding unit and the second flow guiding unit are actuated, gas is inhaled through the respective inlets and discharged out through the respective outlets. A gas-collection chamber is disposed between the first flow guiding unit and the second flow guiding unit and includes a discharging opening. The gas is inhaled through the inlets of the first flow guiding unit and the second flow guiding unit, and transported to the gas-collection chamber through the outlets thereof. The gas in the gas-collection chamber is discharged out through the outlets of the first flow guiding unit and the second flow guiding unit, to achieve an adjustment of gas transportation amount.

A gas transportation device is provided and includes a plurality of flow guiding units. Each of the flow guiding units includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric component, an outlet plate and a valve, which are sequentially stacked. A convergence chamber is formed between the resonance plate and the inlet plate. The actuating plate has a suspension part, an outer frame and a plurality of interspaces. The piezoelectric component is attached on a surface of the suspension part. Gas is inhaled into the convergence chamber via an inlet aperture of the inlet plate, is transported into a first chamber via a central aperture of the resonance plate, is further transported into a second chamber via the interspaces, and is discharged out from an outlet aperture of the outlet plate. The gas is transported by the flow guiding units disposed in a specific arrangement.

A swash plate compressor includes a cylinder block accommodating a piston for compressing a refrigerant, a front housing coupled to the cylinder block and having a crank chamber, a rear housing having a suction chamber and a discharge chamber and coupled to the cylinder block, and a suction reed plate inserted between a valve plate and the cylinder block. The swash plate compressor includes: a first orifice hole through which the refrigerant in the crank chamber passes; a second orifice hole communicating between the first orifice hole and the suction chamber; an intermediate flow path configured to connect the first orifice hole and the second orifice hole; and the valve plate inserted into the rear housing and having a suction chamber pressure-maintaining space connected to the suction chamber and configured to maintain a pressure equal to a pressure in the suction chamber.

A compressor valve plate (80) for a reed valve (94) has a mounting surface portion for mounting a base portion (104) of a reed (100). The compressor has a port (90). A seat (150) surrounds the port. A trepan (154) surrounds the seat. A relieved area (180, 182) less deep than the trepan extends proximally (182) of and distally (180) of the trepan. A reciprocating piston compressor comprises a valve assembly having such a compressor valve plate and a reed.

Compressor for generating compressed air for a commercial vehicle, having a housing with a piston chamber in a crankcase and a dead space which is configured at least in the cylinder head. The compressor has a valve device with a valve element which has an actuating section and a shut-off body for separating the dead space from the piston chamber, wherein the shut-off body can be lifted up from a valve seat in the direction of the piston chamber in order to open the valve device. The valve element is configured in one piece with the actuating section.

According to the present invention, there is provided a compressor including: a piston reciprocated in a cylinder; a valve seat plate provided with a port through which a fluid passes along with the reciprocation of the piston; a valve provided in the valve seat plate to open/close the port; a valve receiver regulating the degree of opening of the valve; and a stress suppression member provided between the valve and the valve receiver, wherein the stress suppression member includes a valve exposing portion exposing the valve.

A reciprocating compressor according to an aspect includes a driving unit; a connecting rod; a piston; a cylinder; and a valve assembly, wherein the valve assembly includes a valve plate forming a main body, a suction inlet and a discharge outlet disposed at the valve plate and coming in communication with a compression space of the cylinder to guide a refrigerant flow, a suction valve and a discharge valve disposed at the valve plate and selectively opening the suction inlet and the discharge outlet, and a plurality of coupling portions disposed at the valve plate, and a plurality of corresponding coupling portions disposed to correspond to each of the plurality of coupling portions and preventing the valve assembly from being erroneously assembled are disposed at the cylinder.

A cylinder coupling structure of a small air compressor according to the present invention, in which a cylinder is integrally coupled to a block by which a crankshaft is shaft-supported, wherein the block is provided with a supporting end by which the cylinder is pressed to be supported; a latching end is formed on the outer surface of the cylinder; and a press bolt is fastened to the block and a valve cover so that the valve cover presses the front end of the cylinder while the latching end of the cylinder is latched and supported on the supporting end.

An apparatus for a compressor head assembly with a discharge valve comprises a valve plate having a first face and a second face, wherein at least one cavity is located on the second face and a reed valve assembly sized to be contained in the at least one cavity. The reed valve assembly comprises a reed valve plate with at least one orifice, the reed valve plate selected according to a rated compressor displacement a retainer portion; and a reed retained by the retainer portion proximate to the reed valve plate and oriented to inhibit air flow through the at least one orifice in a closed state. The reed valve assembly is removably secured to the valve plate to facilitate changing the characteristics of the reed valve assembly without changing the valve plate.
