An air compressed gun (10) is provided having a stock (11), a barrel (12), a pressure chamber (16), a pressure actuatable release valve (18) and a manual air pump (14). The pump has an elongated cylinder (25) having a port (38) in fluid communication with the release valve, and a plunger (26) telescopically mounted for reciprocal movement within the cylinder. The plunger has an O-ring type seal (31). The forward movement of the plunger seal towards the port pressurizes air within the cylinder which is transferred to the release valve and pressure chamber. The continued movement of the plunger seal past the port causes a portion of the pressurized air to be released so as to actuate the pressure actuatable release valve to release the pressurized air within the pressure chamber into the barrel.

A compressed air launcher comprising: a launch tube; a pressure actuatable release valve for controlling the flow of pressurized air into said launch tube; a conduit having a first end coupled to said pressure actuatable release valve and a second end opposite said first end; and a combination air pump and triggering means comprising an elongated cylinder having a first end and a second end, a port spaced from said first end and spaced from said second end, said port being coupled in fluid communication with said second end of said conduit, and a plunger having a seal movably mounted in said elongated cylinder for reciprocal movement, whereby movement of the seal within the cylinder in a direction from the first end toward the port causes air in the cylinder and the conduit to be pressurized thereby maintaining the pressure actuatable valve closed, and whereby movement of the seal within the cylinder past the port and toward the second end causes air in the conduit to be released into the elongated cylinder behind the plunger seal, to cause a pressure drop which actuates the pressure actuatable valve to open.
