Abstract: PROBLEM TO BE SOLVED: To suppress bubbles and gas-enriched liquid separated from liquid in a gas-liquid separation chamber from leaking out of an air release hole.SOLUTION: A float valve 70 of a pump unit includes: a float 72 vertically moving according to a liquid level height in a gas-liquid separation chamber 36; a support rod 74 for supporting the float 72; and a first valve portion 76 and a second valve portion 78 that are connected with the support rod 74. The first valve portion 76 opens and closes a flow path 78b in conjunction with up-and-down movements of the float 72, and opens the flow path 78b at a valve opening degree corresponding to a raised position of the float 72 when a liquid level in the gas-liquid separation chamber 36 has a height H1 or less height. The second valve portion 78 is configured so that, a long hole 78d may come in contact with a connecting pin 74a to perform a valve opening operation when the float 72 rises up by a predetermined angle. Thus, a valve element 78a of the second valve portion 78 maintains its closed state until the float 72 reaches a predetermined height H2, and opens a return hole 60 provided in the bottom of the gas-liquid separation chamber 36 when the float 72 reaches the predetermined height H2.

Title: Method of reducing shearing locking of 8-node hexahedron element in finite element method
Inventor: THOMAS BORRVALL
IPC: G06Q50/00
Filed: 2011-01-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide an improved 8-node hexahedral element constituted to reduce shearing locking in a finite element method.  <P>SOLUTION: Each scale factor based on an aspect ratio is introduced to modify a partial derivative of an isoparametric shape function of each hexahedral element with respect to isoparametric dimensions, according to one aspect. The modified derivatives are used for calculating a Jacobian matrix, thereby the rate-of-strain. The scale factor is configured to bring no changes for a perfect cubic solid element, but to bring a significant change for the element having a poor aspect ratio. Off-diagonal components in a local Jacobian matrix are directly modified by canceling terms related to a pseudo shear deformation mode. This measure completely alleviates the shear locking effect even for perfectly shaped elements, according to another aspect.  <P>COPYRIGHT: (C)2011,JPO&INPIT
