Abstract: A casing includes a first plate made of a metal, a support made of a resin, and a second plate fixed to the support. The first plate includes a flat plate portion, a through hole passing through the flat plate portion, and a claw portion extending upward from an edge of the through hole. A portion of the support is located in the through hole. The support covers a portion of the claw portion such that the support is prevented from turning and from coming off in an upward direction. The claw portion is defined by a portion of the first plate extending along a longest line segment inside the through hole in a plan view being bent upward from the flat plate portion. This enables the claw portion to have a great length even in a small area of the first plate to securely fix the support to the first plate.

Abstract: A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.

Abstract: A turbocharger compressor cover (114) including an inner shroud contour (122) configured to receive a compressor wheel (118) having a plurality of blades (140). Each blade (140) includes a leading edge (142), a contour edge (144), and a trailing edge (146). An inlet passage (124) leads to the inner shroud contour (122) and a circumferential groove (130) is formed around the inlet passage (124). The groove (130) includes a trailing edge (136) that is aligned with the outboard end (148) of the leading edge (142) of the blades. The compressor cover (114) includes an edge relief (138) formed along the groove trailing edge (136), such as a 45 degree chamfer. The circumferential groove (130) has a width and a depth, wherein the width and depth are approximately equal. The chamfer intersects the groove (130) approximately half the depth from the bottom of the groove (130).

Abstract: A valve (10) for the temperature-dependent control of at least one hydraulic load includes a valve housing (12) with a tank connection (T), a working connection (A), and a supply connection (P). A control piston (30) controls the connections (A, P, T), is moveable in the valve housing (12) and is preloaded by a working spring (74). A thermal element (62) can be supplied with a fluid at a specifiable temperature (TFIuid) and is actively coupled to the control piston (30). The control piston can be moved by control pressure present at the supply connection (P). The thermal element (62) interacts with the working spring (74) such that the thermal element causes a temperature-dependent change of the preload force acting on the control piston (30).

Abstract: A product usable with a turbocharger may include a compressor wheel having an inducer section and an exducer section. Air may be collected by the inducer section and expelled by the exducer section. A cover may define a diffuser and a collection volute. The diffuser may lead away from the exducer section to the collection volute. The cover may define a collection cavity opening to the collection volute through a port and extending in an axial direction. The cover may define an inlet passage around the inducer section and the cover may include a dividing wall separating the inlet passage from the collection cavity.
