An air compressor includes a cylinder housing, an outlet receptacle disposed on the cylinder housing, and a partition formed between the cylinder housing and the outlet receptacle and having an air passage formed in the partition, a piston slidably received in the cylinder housing and coupled to a motor for moving relative to the cylinder housing in a reciprocating action in order to generate a pressurized air, and a spring-biased check valve engaged with the partition for selectively blocking the air passage of the partition, the outlet receptacle includes an inner diameter “D2” no less than an inner diameter “D1” of the cylinder housing for allowing the pressurized air to easily flow into the outlet receptacle and for allowing the piston to be moved in a greater moving speed. |

1. An air compressor comprising:
a cylinder housing including a chamber formed therein, an outlet receptacle provided on said cylinder housing and including a compartment formed therein, and including a partition provided between said cylinder housing and said outlet receptacle, and including an air passage formed in said partition and communicative with said chamber of said cylinder housing for receiving a pressurized air from said chamber of said cylinder housing, and communicative with said compartment of said outlet receptacle, a piston slidably received in said chamber of said cylinder housing and having a piston rod extended therefrom, a motor coupled to said piston for moving said piston relative to said cylinder housing in a reciprocating action in order to generate a pressurized air and for allowing the pressurized air to be supplied from said chamber of said cylinder housing to said compartment of said outlet receptacle, and a spring-biased check valve disposed in said outlet receptacle and engaged with said partition for selectively blocking said air passage of said partition and for guiding the pressurized air to flow from said chamber of said cylinder housing into said compartment of said outlet receptacle, and to prevent the pressurized air from flowing backwardly from said compartment of said outlet receptacle into said chamber of said cylinder housing, wherein: said compartment of said outlet receptacle includes an inner diameter D2 no less than an inner diameter D1 of said chamber of said cylinder housing, said outlet receptacle includes a cover having an extension extended into said compartment of said outlet receptacle and extended and directed toward said check valve, and a spring biasing member engaged between said extension of said cover and said check valve for biasing and forcing said check valve to selectively engage with said partition and to selectively block and seal said air passage of said partition, and said outlet receptacle includes a peripheral wall extended into said compartment of said outlet receptacle and located around said extension for forming an annular space between said extension and said peripheral wall and for partially engaging with said pegs. |
