Valve seats include a flexible arm portion configured to seal against a portion of a valve body of a valve. A ball valve may include such valve seats. Methods of forming a seal in a ball valve include forcing a first metal valve seat into sealing contact with a first end cap and a ball valve member with a first metal flexible arm member and forcing a second metal valve seat into sealing contact with a second end cap and the ball valve member with a second metal flexible arm member.

Valve assemblies, valve seats including flexible arms, and related methods

Valve seats include a flexible arm portion configured to seal against a portion of a valve body of a valve. A ball valve may include such valve seats. Methods of forming a seal in a ball valve include forcing a first metal valve scat into sealing contact with a first end cap and a ball valve member with a first metal flexible arm member and forcing a second metal valve seat into sealing contact with a second end cap and the ball valve member with a second metal flexible arm member.

A connection between a fluid filter and a head is described that permits quick connection/disconnection between the two without requiring disconnection of fluid lines from the head. The head includes a lock to connect inlet and outlet fluid lines to a fluid filter using a non-threaded attachment method. The lock that retains the head to the fluid filter is flexible to allow for connection and disconnection. The head has fluid inlet and outlet ports to which fluid lines attach to flow unfiltered fluid into and filtered fluid out of the fluid filter when the head is connected to the fluid filter. The head closes the fluid filter, which has a protrusion with adjacent passageways that guide and separate unfiltered from filtered fluid.

A filter cartridge is described that is designed to accommodate for example dual stage filtration. The filter cartridge has an endplate structure formed of a heat cured material, such as polyurethane, where at least one of the top end and the bottom end of the outer filter and the inner filter are embedded within the heat cured material. The heat cured material can provide an endplate structure that is convenient for manufacture and that has one or more sealing surfaces to seal with a housing that the filter cartridge is assembled with. For example, the heat cured material of the endplate can seal non-filtered fluid from filtered fluid that has passed through each of the filtration stages available in the cartridge.

A fuel water separator system includes a fuel tank for storing fuel and a fuel water separator fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side that is fluidly coupled to the fuel water separator for pumping fuel from the fuel water separator. The fuel pump has a high pressure side where the fuel has a higher pressure than at the suction side. A water pump, such as a venturi or a jet pump, is fluidly coupled between the fuel water separator and the fuel tank for pumping the water from the fuel water separator into the fuel tank. The water pump is fluidly coupled to the high pressure side of the fuel pump to receive the fuel at the higher pressure to drive the water pump.

A filter system includes a filter configured to regulate fuel pressure as well as automatically vent air from the filter. A pressure regulator valve is positioned in the top of a standpipe of the filter. The filter includes a filter cartridge with top and bottom end caps. The top end cap of the filter cartridge has a hole with radial sealing gasket, which seals against the top of the standpipe to prohibit flow from bypassing the filter cartridge. This arrangement exposes the regulator valve to the fuel and/or air at the top of the filter housing. Pressure in the housing opens the valve, allowing air and/or fuel to be vented through the standpipe, and back to the fuel tank.

A priming pump for fluid delivery arranged with a base defining a flow inlet, a flow outlet, and a control valve positioned therebetween. The priming pump includes a housing assembled to the base with an inlet flow valve positioned in an inlet valve compartment and an outlet flow valve positioned in an outlet valve compartment. The valve compartments are in communication with a plunger chamber including an axially movable plunger. A spring-biased control knob is assembled to the plunger and to the control valve for controlling its position between either a direct-flow orientation or a by-pass orientation. With the control valve in the by-pass orientation, upward movement of the control knob draws fluid into the inlet valve compartment and into the plunger chamber. The down stroke of the control knob pushes the fluid out of the plunger chamber.

An interchangeable flashlight-cargo lamp system includes a docking station that is suitable for mounting either a cargo lamp or a rechargeable flashlight. The flashlight doubles as a cargo lamp when mounted within the docking station. Both the cargo lamp and the flashlight have common mounting elements that mate with corresponding mounting features of the docking station to permit either device to be inserted into and removed from the docking station. The interchangeable devices also include electrical contacts that mate with corresponding electrical contacts in the docking station. The flashlight further includes a battery that is recharged when the flashlight is mounted in the docking station.

A fuel-water separation filtration system for filtering fuel and for separating water out of the fuel includes a housing assembly, a filter element assembly, and a closing lid. The housing assembly includes a unitary molded housing, a plurality of flow connection fittings that are spin welded into the housing, and a standpipe that is spin welded to the housing. The filter element assembly includes a cover and an endplate and filter media with one end bonded to the cover and an opposite end bonded to the endplate. The standpipe includes an attachment portion that extends beyond the upper end of the filter element assembly and the closing lid is threadedly attached to the attachment portion for closing the housing assembly. The filtration system requires pressurization for proper operation and the filtration system cannot be pressurized without the filter element assembly being installed.
