ABSTRACT:
A pressure limiting device for protecting a fluid pressure circuit involves a stack of elastomeric washers, and each of the washers has a slit through which fluid can bleed to reduce the fluid pressure below a critical value; the slits are normally closed and so prevent substantial fluid flow, but are able to open to pass fluid when the pressure reaches a critical value at which the pressure distorts the stack of washers.
