Patent number: 11306589Abstract: A rotary displacement piston pump is disclosed having rotatable single or dual valve/port plate(s). The valve plate, being rotatable forward and/or rearward with respect to the rotation of the piston carrier, alters the phasing of the land area of the pumping action thereby altering the phasing of piston speed inasmuch as the land area can be moved to a position to accelerate the piston(s) in a pre or decompression phase. In this way, pump noise, from colliding pressure fronts within the respective high and low pressure plenums, can be “tuned” out of the pump by adjusting the phasing and position of the valve plate(s) and raising or lowering the pre and decompression pressure(s) as necessary. Pump volume can also be controlled by advancing or retarding the valve plate(s), either in or out of synch, so as to shorten intake/exhaust piston stroke and overlap fluid flow between respective intake/exhaust plenums.Type: GrantFiled: March 29, 2021Date of Patent: April 19, 2022Assignee: Volvo Construction Equipment ABInventors: Andreas Tonnqvist, Jonas Forssell, Jan-Ove Palmberg, Liselott Ericson, Anders Hedebjörn

Patent number: 6705670Abstract: A stabilized frame assembly 32 for a motor vehicle 10 including a pair 34 of forwardly directed brace members 36, 38. Each brace member 36, 38 of the pair 34 is coupled at a forward end 40 to an impact receiving assembly 46 such as a front bumper assembly. The brace members 36, 38 are coupled for support at a rearward end 42 to a respective one of a pair 48 of stabilized support arrangements 50, 52. Each of the stabilized support arrangements 50, 52 are configured to resist deformation under the influence of crash related impact forces having magnitudes in a manageable design range for the stabilized support arrangement 50, 52. Each of the pair of stabilized support arrangements 50, 52 are constructed to include a plurality of support legs 56 that are configured so that loads or forces transmitted from the supported brace member 36, 38 to the stabilized support arrangement 50, 52 are distributed as substantially axial loads in the plurality of support legs 56.Type: GrantFiled: June 1, 2001Date of Patent: March 16, 2004Assignee: Volvo Car CorporationInventors: Jonas Forssell, Andréas Tonnqvist, Mats Boberg, Martin Swahn, Egon Strandberg, Tom Stoddart, Stina Jonsell, Martin Wedel, Martin Weiman, Thomas Broberg
