Abstract
Aspects of the disclosure relate to an overload protection valve for automatic release of a load. The valve may include an outer housing having an end wall, a cam, and inner slide, and an overload spring. The inner slide may include a side wall, a shelf area, an internal barrier, an inlet and an outlet. Each of the inlet and outlet may include an opening through the side wall, and the inlet and the outlet may be separated by the internal barrier. The overload spring may be arranged between the end wall and the shelf area, and may define a load on the valve which will cause the valve to open. The cam may be configured such that when the valve is closed, the defined load will cause the cam to rotate thereby allowing the openings of the inlet and outlet to be in fluid communication and open the valve.
