Embodiment Construction

[0017] Referring to the figures, a pneumatic cylinder actuator according to the invention is indicated generally with the reference numeral 10 .

[0018] The cylinder actuator 10 includes:

[0019] - tubular housing jacket 11,

[0020] - two opposite heads 12 and 13 for closing the tubular casing 11 together with corresponding sealing elements between the heads and the casing, the first head 12 being provided with a through-hole 14 for the passage of the rod-piston 15, And the second head 13 is provided with a gas filling duct 16,

[0021] - rod-piston 15,

[0022] Between the tubular jacket 11 , the head 12 and the head 13 and the rod-piston 15 there is a chamber 17 for pressurized gas.

[0023] The cylinder actuator 10 is characterized in that the second head 13 has a seat 18 for accommodating the flow control element 19 of the gas-filled duct 16 and the corresponding sealing means 20 .

[0024] The flow control element 19 comprises a lug 21 for controlling the retractio...

Abstract

The invention relates to a pneumatic cylinder actuator with a safety device, comprising: a tubular housing casing (11), two opposing heads (12, 13) for corresponding sealing elements between the heads and the casing close together the tubular casing (11); the first head (12) is provided with a through-hole (14) for the passage of the rod-piston (15), and the second head (13) is provided with a gas-filled duct (16), the rod -piston (15), between the tubular casing (11), the head (12, 13) and the rod-piston (15) there is a chamber for pressurized gas (17); the second head (13) has a A seat (18) for accommodating a flow control element (19) of a gas-filled conduit (16) and a corresponding sealing means (20), the flow control element (19) comprising a control rod-piston (15) retraction stroke The lug (21), the control lug (21) protrudes from the main body (22), which has a lightening part (23) for the control lug (21) being pressed by the rod-piston ( 15) Trigger controlled fracture or deformation in case of extrusion.

Description

technical field [0001] The invention relates to a gas cylinder actuator with a safety device. Background technique [0002] Cylinder actuators generally have a tubular containment jacket that is hermetically closed at one end by a first perforated head for a piston that translates inside the jacket. The rod passes through and is hermetically closed at the other end by a second head having a hole or duct provided with a check valve for the discharge of gas; the casing, the end face and the head delimit the piston The travel space, while the piston itself, together with the outer casing and the end faces, delimits the gas compression and expansion chambers in the head that exist within the cylinder actuator. [0003] Such cylinder actuators are also typically, but not exclusively, used in situations such as the use of mold dies, mold presses, and the like, where such cylinder actuators may experience pressure such that They are susceptible to damage; such damage may render t...
