Patent number: 11187308Abstract: An actuator for driving a rotatable component includes a first, rotating member comprising a screw and a second member comprising a nut threaded to said screw, wherein rotation of said first member causes axial movement of said first or second member. The component also includes a third member coupled to the second member, wherein axial movement of said first or second member causes axial movement of said third member and a fourth, rotating member coupled to said third member and connectable to said component. The system also includes a bearing system located between said third member and said fourth member, said bearing system configured to cause said fourth member to rotate upon said axial movement of said third member so as to drive said component.Type: GrantFiled: June 26, 2019Date of Patent: November 30, 2021Assignee: HS WROCLAW SP. Z O. O.Inventor: Daniel Trybula

Patent number: 10794502Abstract: A check valve comprises a valve housing defining a valve opening; and a flapper element. The flapper element has a proximal end, and is pivotally mounted to the valve housing adjacent the periphery of the valve opening at its proximal end for pivotal movement between a closed position, in which it blocks the flow of fluid through the valve opening and a fully open position in which it permits the flow of fluid through the valve opening. At least one spring damping element is located between the flapper element and the valve housing for providing a damping force resisting the pivotal movement of the flapper element towards its open position. The at least one spring damping element being operable to produce a damping force only over a final range of the pivotal movement of the flapper element as it approaches its fully open position.Type: GrantFiled: June 21, 2018Date of Patent: October 6, 2020Assignees: HS WROCLAW SP.

Patent number: 10072767Abstract: A check valve includes a housing including a septum separating at least two openings formed therein, the openings being defined by an outer edge and one or more petals pivotably coupled together along the septum to occupy respective open and closed positions in accordance with a pressure differential of a fluid flow across the check valve. In this aspect, a cut height of the septum is greater than a cut height of at least a portion of the outer edge.Type: GrantFiled: October 16, 2015Date of Patent: September 11, 2018Assignee: HS WROCLAW SP. Z O.OInventor: Modest Adam Reszewicz

Patent number: 9982818Abstract: A shape memory alloy (SMA) sealing ring is deformed to provide a shape between a radially inner sealing portion and radially outer sealing portion thereof which has at least one peak and at least one trough. When the shape memory behavior of the SMA is activated, this shape provides a sealing connection between a first and second member.Type: GrantFiled: November 10, 2016Date of Patent: May 29, 2018Assignee: HS WROCLAW SP.

Patent number: 9976662Abstract: A pressure relief valve includes a valve element having, at one end, a flow restricting head and, at an opposed end, a damping head. The damping head includes a damping channel formed therein to allow fluid flow between an inlet chamber and a damping chamber of the valve.Type: GrantFiled: March 18, 2016Date of Patent: May 22, 2018Assignee: HS WROCLAW SP. Z O.OInventor: Stefan Trotzko

Patent number: 9803761Abstract: A check valve includes a housing, a flap, a hinge, at least one post, and at least one tubular bumper. The hinge allows the flap to rotate relative to the housing between a fully open position and a closed position. The at least one post is disposed at or near the periphery of the housing supporting the hinge and extending axially relative to the housing from the housing. The at least one tubular bumper is movable with the flap and configured to contact the at least one post when the flap pivots to the fully open position.Type: GrantFiled: April 12, 2016Date of Patent: October 31, 2017Assignee: HS Wroclaw Sp.
