Abstract
A hand pump includes a piston slidably engaged in a housing and coupled to a piston rod, a handle attached to the piston rod for moving the piston along the housing in the reciprocating action in order to pump and generate a pressurized air and to supply the pressurized air out through the outlet port of the housing, the piston is selected from a magnetic member, and a coil is engaged onto the housing and disposed around the piston for generating an electrical energy when the piston is moved relative to the housing and the coil. The piston includes one or more recesses for receiving the pressurized air and for buffering purposes. A cover is attached to the housing and includes a space for buffering purposes.
Claims13
A hand pump comprising:
- a housing including a chamber formed therein, and including an outlet port provided therein,
- a piston slidably received and engaged in said chamber of said housing and movable along said chamber of said housing in a reciprocating action in order to pump and generate a pressurized air and to supply the pressurized air out through said outlet port of said housing,
- a piston rod including an inner end portion attached to said piston for actuating said piston to move along said chamber of said housing in the reciprocating action, and including an outer end portion extendible out of said housing, and
- a handle attached to said outer end portion of said piston rod for actuating said piston to move along said chamber of said housing in the reciprocating action, wherein:
- said piston is selected from a magnetic member, and a coil is engaged onto said housing and disposed around said piston for generating an electrical energy when said piston is moved relative to said housing and said coil.
