Aspects of the disclosure relate to grabbing, holding and releasing an object including a pull stud. For instance, a grabbing mechanism may include a piston chamber having a piston configured to move within the piston chamber when the piston chamber is pressurized. The mechanism may also include a collet attached to the piston such that the collet and piston move together when the piston moves. The collet may include a groove. The mechanism may also include ball cage including a plurality of balls arranged at least partially within respective ball chambers of the ball cage. The ball cage may be arranged at least partially within the collet such that movement of the piston and collet causes the groove to align with the respective ball chambers. The plurality of balls may be configured to move into and out of the groove and to lock the pull stud within the mechanism.

Grabbing mechanism

Aspects of the disclosure relate to a fluid connector mechanism having an opening therethrough. The mechanism may include a connector having a connector base portion and a piston portion including a piston housing and a piston. The opening may extend from the piston portion, through the piston, and through the connector base portion. The mechanism may also include a base having first and second pairs of O-rings arranged in first and second pairs of grooves, the opening further extending from one end of the base to another. The connector base portion and the base may be configured to engage with one another and create fluid-tight seals with the O-rings while the piston is arranged outside of the base.

Multi port fluid connector

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.
