Abstract:
    A hydraulic stunner apparatus for use in slaughtering animals includes a housing (10) that defines a cylinder (14) within which a rear seat (75) is disposed. An elongated stunner element (12) is received in and closes off the front end of the cylinder. The stunner element (12) is movable between a cocked position in which the first end of the element (12) is sealed against the seat (75), and a fired position in which the first end of the element (12) is unseated and the stunner element is extended relative to the cylinder. Hydraulic fluid under pressure is directed into the cylinder to pressurize the cylinder, and an actuator (116) is provided for unseating the stunner element (12) from the cocked position to initiate movement of the element to the fired position. Preferably, the apparatus also includes a compressible biasing assembly (24, 122) for maintaining the hydraulic pressure within the cylinder upon separation of the stunner element from the seat and movement of the stunner element toward the extended position.
