Closing device for a pressure accumulator, torpedo with a pressure accumulator and said closing device for the pressure accumulator and use of said closing device for the closure of a pressure accumulator of a torpedo

Abstract

The invention relates to a locking device for a pressure reservoir. The invention also relates to a torpedo with a pressure reservoir with a locking device of this type and the use of a locking device of this type for the pressure reservoir of a torpedo. The locking device ( 1 ) has an inlet side ( 3 ) and an outlet side ( 4 ), together with a locking element, which fluidically controls a connection between the inlet side ( 3 ) and the outlet side ( 4 ). Further, the locking device ( 1 ) has an actuator ( 11 ) to actuate the locking element. In order to guarantee the envisaged operating pressure in the pressure reservoir, even after several years' storage, it is provided in accordance with the invention that the locking element is a sealing membrane ( 5 ) and the actuator ( 11 ) has an opening spike ( 12 ), arranged so as to be movable, in whose path of travel the sealing membrane ( 5 ) is located.

 wherein   at least one groove is formed on the circumference of the opening spike, wherein the grooves are designed in the direction of movement of the opening spike, wherein multiple grooves are arranged at equal distances on the circumference of the opening spike.   
     
     
         8 . The locking device in accordance with  claim 1 ,
 wherein   the actuator incorporates an adjusting screw, which can be driven so as to rotate, and an adjusting screw acting in concert with a spindle nut, which is guided longitudinally and bears the opening spike, wherein the spindle nut is guided longitudinally on the housing of the locking device.   
     
     
         9 . The locking device in accordance with  claim 1 ,
 wherein   the actuator comprises an electric drive motor, wherein the adjusting screw is driven by the drive motor.   
     
     
         10 . The locking device in accordance with  claim 1 ,
 wherein   the opening spike is guided in the housing of the locking device, comprising position sensors arranged in the area of the opening spike guide, fixed in place on the housing, which act in concert with a locator, which can be moved with the opening spike, wherein the locator is a magnet and the position sensors are Hall sensors.   
     
     
         11 . The locking device in accordance with  claim 10 ,
 wherein   the position sensors comprise three position sensors arranged in a line, wherein the middle position sensor corresponds with an inactive state of the locking device with an intact sealing membrane.   
     
     
         12 . The locking device in accordance with  claim 7 ,
 wherein   a spindle nut is guided on its circumference on the housing, wherein a seal is arranged on the circumference of the spindle nut, wherein the seal is a circumferential O-ring.
