Why "Pinched Bladder" will never occur on a NACOL accumulator.

When oil flows out of the NACOL accumulator, the bladder expands and comes in contact with the large rubber cushion cup riveted to the top of the poppet.
Flexing of the large rubber cushion cup prevents the bladder from bulging around and under the poppet. Therefore, the NACOL bladder can never be pinched by the poppet. This patented feature eliminates one of the major causes of accumulator failure.
