Patent number: 7147002Abstract: A multi-function fluid flow control device is disclosed. A body houses a filter screen, a check valve and an orifice plate mounted on a frame which is removable from the body as a unit through an opening in the body sealed by a removable plug. The orifice plate is removable from the frame to permit different sized orifices to be fitted. An inlet in the body conducts pressurized fluid through the filter screen, through the check valve and then out through an outlet in the body, both the inlet and outlet being adapted for convenient connection to a piping network. An opening in the body in fluid communication with the inlet and sealable by a removable plug allows the screen to be flushed for removal of debris.Type: GrantFiled: October 28, 2003Date of Patent: December 12, 2006Assignee: Victaulic CompanyInventor: William J.

Patent number: 7131461Abstract: An improved double block and double bleed stream switching system (modifiable to, for example, a double block, single bleed stream switching system) includes a common stream path for a multitude of gas streams from, for example, a process pipeline. The improved stream switching system includes a heating mechanism and insulation oven to help temperature stabilization, along with a structure to separate temperature sensitive solenoids from the heated area. Pre-heat coils are located between the sample switching system and the sample shut off system to warm the gas sample and to act as a flow restrictor. A first embodiment is suited for the Division 1 environment and a second embodiment is suited for Division 2 uses. The improved stream switching system may also feature membrane or cartridge filters located upstream of the sample wetted portion of the stream switching system.Type: GrantFiled: March 30, 2000Date of Patent: November 7, 2006Assignee: Daniel Industries, Inc.Inventors: Yang Xu, Teresa Lechner-Fish

Patent number: 7069947Abstract: A fluid control valve includes a valve body, an annular groove portion formed in an outer periphery of the valve body, a filter provided in the groove portion. The filter includes a plate with a plural of perforations and formed into a cylindrical shape. The filter further includes a snap ring formed from a thin bar bent into a loop. Both ends of the snap ring extending in an axial direction and freely contacting with opposed side surfaces defining the groove portion.Type: GrantFiled: February 25, 2004Date of Patent: July 4, 2006Assignee: Aisin Seiki Kabushiki KaishaInventors: Kazuhiko Maeda, Shigeki Niimi, Kazuhiro Matsukawa, Hiroshi Isogai

Patent number: 7000633Abstract: A filter is annularly attached around a peripheral wall of a housing. The filter is composed of a filtering element that covers a fluid passage for inhibiting foreign objects from entering, a supporting portion for supporting the filtering element, and a connecting portion for connecting between both ends of the supporting portion. The connecting portion is narrower than the supporting portion. The filter is movable radially in two directions according to a clearance between the filter and the housing. A contact portion is formed, with being able to be slid within a movable range of the filter, between an outer surface portion of the peripheral wall that surrounds an opening of the fluid passage and an inner surface portion of the filter that surrounds the filtering element.Type: GrantFiled: June 6, 2003Date of Patent: February 21, 2006Assignee: Denso CorporationInventors: Motohiro Okada, Mitomu Mohri

Patent number: 6915818Abstract: A fluid pick up device for removing fluid from storage tanks includes an intake, a submerging member that maintains the intake submerged in the fluid, and a float that enables the intake to move in relationship to the level of fluid. The submerging member can include an extension communicating with the intake. The extension can be an adjustable arm connected to a delivery member by a swivel joint. A stopping member can control the arm's range of motion. The intake is angled downward, and the length of the arm is set to prevent the intake from passing into a contaminated volume of fluid near the tank bottom. The intake can also be movable. The adjustable arm can retract into the delivery member.Type: GrantFiled: March 4, 2004Date of Patent: July 12, 2005Assignee: Fuel Delivery Systems, LLCInventors: Steven Y Burris, Charles A. Perry, IV

Patent number: 6913040Abstract: A hydraulic fluid reservoir apparatus for an automotive power steering system comprises a filter chamber, and a filter parallel to a vertical axis and dividing the filter chamber into an upstream region and a downstream region. The reservoir apparatus also includes a stagnant fluid well apart from the filter chamber, and a de-aeration zone overlying the filter chamber. A vent is provided between the upstream region and the de-aeration zone. Fluid recycled to the reservoir apparatus contains entrained gas. The filter separates the gas from the fluid within the upstream region, whereupon the gas is vented to the de-aeration zone and separates from the fluid circulated to the stagnant fluid well.Type: GrantFiled: March 24, 2003Date of Patent: July 5, 2005Assignee: Visteon Global Technologies, Inc.Inventors: John Crossman, Neil Lauer, Stuart Dale Barter
