Patent number: 11518452Abstract: A vehicle suspension position adjustment arrangement including a frame member having a plurality of apertures, and a trailing arm having a first end pivotally coupled to a slide member and a second end biased away from the frame member. A locking pin movable between an unlocked position where the locking pin is withdrawn from one of the apertures and the slide member is free to slide along the frame member, and a locked position where the locking pin engages one of the apertures preventing the slide member from sliding along the frame member, and a plurality of sensors spaced along the frame member, wherein a single sensor of the plurality of sensors is configured to sense both the locking condition of the locking pin and the location of the locking pin along the frame member.Type: GrantFiled: June 5, 2020Date of Patent: December 6, 2022Assignee: SAF-Holland, Inc.Inventors: Randy L. Schutt, Ahmad Nizam Mohamad Jembari, Thomas D. Stoll

Patent number: 5683229Abstract: A refrigeration system is disclosed in which negative energy storage is provided to significantly reduce electrical energy consumption during peak air conditioning hours. A transfer pump is provided in the system for pumping condensed and mixed phase refrigerant from the negative energy storage to an evaporator coil where it absorbs heat energy from an air conditioned space. The transfer pump is a positive displacement pump employing a rotor and vanes rotating in a pumping chamber. Dual inlets and discharges from the pumping chamber are located to balance forces on the rotor. The inlets enter the pumping chamber radially. A hermetic enclosure seals the pump and an electric drive motor to eliminate dynamic seals within the pump and thereby greatly reduce leakage of refrigeration from the system. A refrigeration overfeed system using a hermetically sealed pump according to the invention is also disclosed.Type: GrantFiled: June 7, 1995Date of Patent: November 4, 1997Assignee: Delaware Capital Formation, Inc.Inventors: Thomas D. Stoll, Lawrence Edward Switek

Patent number: 5571005Abstract: A hinged vane rotary pump including a cylindrical chamber, a rotor eccentrically mounted within the chamber, and a plurality of vanes. Each vane is hinged for pivoting movement at its approximate middle to balance hydraulic pressure across the face of the vane. The balanced pressure reduces the force applied by the vane against the chamber liner and therefore reduces wear. As one end of each vane wears against the chamber liner during operation, the axis effectively moves to the center of the vane. Preferably, stops are provided to limit movement of the vanes after maximum wear has occurred.Type: GrantFiled: June 7, 1995Date of Patent: November 5, 1996Assignee: Delaware Capital Formation, Inc.Inventors: Thomas D. Stoll, William J. Bohr
