A blower drive system for a vehicle such as a vacuum truck includes a blower including a blower input shaft and a blower housing; a transfer case operably connected to transfer drive from the vehicle engine driveline to the blower input shaft; a frame bracket assembly including one or more connections to the vehicle chassis frame and one or more connections to the blower housing. The frame bracket assembly mounts the blower housing in a specified fixed angle with respect to ground and mounts the bottom of the blower housing in a specified fixed height above the vehicle chassis frame.

The dynamic fatigue and hysteresis performances of fiber reinforced rubber compounds are compared using different plasticizers. Polymer-based fiber reinforced rubber compounds including a non-linear functionalized fatty acid ester, preferably a trimellitate, and more preferably Tris (2-Ethylhexyl) Trimellitate (TOTM) are shown to demonstrate greatly improved dynamic fatigue and hysteretic performance as compared to reference fiber reinforced rubber compounds including conventional reference plasticizers such as Di-isodecyl phthalate (DIDP).

Scroll compressor includes a shaft rotatably supported to a casing; an eccentric bush having a recess part into which one end portion of the shaft is inserted, an eccentric part eccentric to the shaft, and a balance weight disposed at the opposite side of the eccentric part with respect to the recess part; an orbiting scroll for performing the orbiting motion in interlock with the eccentric part; and a fixed scroll for forming a compression chamber together with the orbiting scroll. The casing has an orbiting groove in which the eccentric bush performs the orbiting motion, a buffer member is interposed between the orbiting groove and the balance weight. Rotation clearance is formed between the recess part and the shaft. The buffer member is compressed between the balance weight and the orbiting groove before the recess part and the shaft contact each other by the rotation clearance.

A compressor includes a casing having a cylindrical portion, a compression mechanism fixed to an inner peripheral surface of the cylindrical portion, an external portion, a weld nut, and a bolt. The external portion includes a temperature reaction portion that reacts to a temperature change of the cylindrical portion. The external portion is mounted on an outer peripheral surface of the cylindrical portion. The weld nut is welded to the outer peripheral surface of the cylindrical portion to mount the external portion on the outer peripheral surface of the cylindrical portion. The bolt fixes the external portion to the weld nut.

A scroll compressor includes a shell that is cylindrical, a fixed scroll fixed to an inner wall of the shell, an orbiting scroll that faces the fixed scroll, a frame fixed to the inner wall of the shell and that supports the orbiting scroll, and a heat source device provided on an outside of the shell and between the fixed scroll and the frame and configured to heat or cool the shell from the outside.

A scroll compressor includes a compressing mechanism unit including a fixed scroll that is fixedly provided in a shell and an orbiting scroll that moves around the fixed scroll, the compressing mechanism unit compressing fluid; a main shaft including an eccentric shaft portion at one end thereof that transmits a rotational driving force to the orbiting scroll; a slider having a slide groove in which the eccentric shaft portion is slidably fitted; and an orbital bearing provided to the orbiting scroll that rotatably supports the slider. The slider is provided on the inner peripheral side of the orbital bearing when seen in a direction of a center axis of the slider. The center axis of the slider is eccentric in one direction from an axis of rotation of the main shaft and a center of gravity of the slider is eccentric in an opposite direction.

Systems are disclosed for power systems and enclosures having an improved compressor drive. In examples, a power system includes a generator to be driven by an engine. The generator is coupled to the engine on a first side of the generator and has a clutch extending from a second side of the generator opposite the engine. The clutch is coupled to the engine. A compressor is positioned at the second side of the generator opposite from the engine. The compressor comprising a shaft extending toward the generator and configured to be driven by the clutch.

Disclosed herein is a scroll compressor having a shaft balancer capable of attenuating vibration while preventing deformation of the rotary shaft during operation at a high speed.
