Abstract: A shock absorber for a vehicle includes a pressure tube that defines a fluid chamber. A piston disposed within the fluid chamber divides the fluid chamber into an upper working chamber and a lower working chamber. The piston defines a compression passage and a rebound passage which extend through the piston between the upper working chamber and the lower working chamber. A valve disc assembly engages the piston and controls the flow of fluid between the upper working chamber and the lower working chamber. The valve disc assembly includes a bleed disc that defines an orifice with a substantially non-linear contour. The orifice extends to an outer diameter of the bleed disc, and forms a bleed channel between the upper working chamber and the lower working chamber.

Abstract: A process challenge device includes a controllable response produced by using a filter material, configured such that a sterilant gas must pass through the filter material to reach the biological indicator (BI). The filter material provides a controllably absorptive barrier, where the absorption of the sterilant is via chemical reaction, through which the sterilant gas must pass to reach the BI.

Abstract: A compressor assembly for compressing a vapor, including a compression mechanism having at least one piston reciprocatingly mounted therein and a motor operably coupled to the compression mechanism. A drive shaft is rotatively mounted in the motor. A rocker mechanism for converting rotational motion of the drive shaft into reciprocating motion of the piston is provided that includes a mounting plate, having an inclined surface, integrally formed with one end of the drive shaft. The rocker mechanism also includes means for linking the mounting plate and the piston so that when the drive shaft rotates, the piston reciprocates within the compression mechanism. The means for linking the mounting plate and the piston is operatively coupled to the mounting plate and is mounted directly to the piston. The means for linking the mounting plate and the piston may include a bearing, a flat plate, or a second plate having an inclined surface.

Abstract: A hermetically sealed compressor assembly including a housing, an electric motor disposed in the housing, a compression mechanism disposed in the housing and operatively coupled to the motor, a cover attached to the housing and including an integral fitting having at least one clip therein. The clip is structured and arranged such that a conduit to be electrically connected to the compressor assembly enters the cover wherein the clip engages the conduit and prevents the egress of the conduit.

Abstract: A reversible reciprocating piston compressor includes a crankcase defining at least one cylinder therein and a crankshaft rotatably supported by the crankcase. The crankshaft includes a drive portion and a crankpin eccentrically positioned relative to an axis of rotation of the crankshaft. A piston is reciprocable within the cylinder and a connecting rod assembly is provided between the crankpin and the piston to reciprocally drive the piston in response to forward or reverse rotation of the crankshaft. A cam assembly is operably connected to the crankpin and is engageable with the drive member to effectuate a first stroke length in a first direction of rotation of the crankshaft and a second stroke in a second direction of rotation of the crankshaft. The cam assembly includes a cam, a driven portion and a counterweight.

Abstract: A reciprocating piston compressor having at least one cylinder, a reciprocable piston disposed in the cylinder, a crankshaft rotatable in both a forward and a reverse direction, the crankshaft having a cylindrical eccentric portion, a latching member pivotally engaged with the crankshaft, a cam disposed about the crankshaft eccentric portion, the piston operatively connected to the cam, and a spring connected to one of the cam and the crankshaft, the position of the latching member influenced by the spring. The cam is rotatable about the crankshaft eccentric portion between a first cam position corresponding to a first piston stroke length during forward rotation of the crankshaft, and a second cam position corresponding to a second piston stroke length during reverse rotation of the crankshaft. In one of the first and second cam positions, the cam is rotatably locked to the crankshaft eccentric portion by the latching member.
