摘要： A pump housing (14, 16) has a fan guard (40) secured to the end of the housing by four crescent-shaped tabs (60) fitting into four crescent-shaped cast-in recesses (66) of the housing (14, 16) and ears (68) of the tabs (60) fitting into cast-in holes (70) in the housing (14, 16). The ears (68) and holes (70) on opposite sides of the housing (14, 16) are aligned along a common axis (80, 82). The ears (68) are tapered at their leading ends (90) and squared off at their trailing ends (92), and the guard (40) has a radial projection (56) that fits into an opening in the housing (14, 16).

摘要： A compact 180° opposed piston pump/compressor minimizes axial spacing between its pistons on the drive shaft and thereby reduces the shaking couple and noise from reciprocation. Each piston has its own eccentric element press-fit into the connecting rods so as not to occupy space between the pistons. The shaking couple can be further reduced for pistons of different masses by selecting the mass of the cup retainers to compensate for the difference in overall piston masses. The pump also includes an improved cylinder sealing arrangement having a circumferential groove in an angled surface at the end of the cylinder. The pump also has a special cover and seal for closing the open neck of the pump crankcase and an improved multi-lobed valve stop. The pump further uses tubular transfer members for transferring intake and/or exhaust air into the crankcase and/or between valve heads.

摘要： Intake or exhaust reed valves of a compressor or vacuum pump have T-shaped flappers which are received in similarly T-shaped pockets so as to be substantially flush with the valve plate. A dirt trap groove is formed in each pocket adjacent to the hinge line of the flapper, a corner relief groove surrounds lands which support the flappers in their associated pockets above the groove, and the extending-part of each pocket widens in the direction away from the cross-part of the pocket. The mating T-shapes of a flapper in a pocket restrain the flapper in the pocket without interfering with the opening and closing motion of the flapper.

摘要： An electronic frequency inverter circuit receives input electrical power at a lower frequency and energizes a load circuit (35) including gaseous discharge lamps (36,37) in a range of higher frequencies. First and second semiconductors (30,31) are operated alternately by a logic circuit (40) in current mode control such that the switches operate at the higher frequency range and the frequency of current in the load circuit varies as the magnitude of said source voltage varies. The load circuit has an impedance (38) which varies with frequency such that the peak amplitude of the load current remains substantially constant despite variations in the magnitude of said source voltage to achieve a desirable crest factor for the lamp current.

摘要： A nutating pump for creating pressure or a vacuum. The nutating pump includes a housing with a center support positioned within said housing. The center support includes a semi-spherical recess. The pump also includes a drive shaft adapted to be connected to an electric motor and an eccentric adapted to be connected to the drive shaft. The pump further includes a ball adapted to form a ball joint and is adapted to be positioned within the semi-spherical recess of said center support. In addition the pump includes a nutating yoke positioned within the housing. The yoke includes a semi-spherical recess adapted to accept said pivot ball. The nutating yoke is adapted to be connected to the eccentric, such that rotation of the eccentric causes the yoke to move about the ball. The pump also includes a connecting rod connected to the yoke, a piston connected to the connecting rod and a cylinder adapted to accept the piston, wherein the movement of the yoke about the ball causes the piston to reciprocate within the cylinder.

摘要： Disclosed herein is an oilless air compressor having a cooling system with a drive unit operating a crankshaft disposed within a crankcase and to which is attached a pair of pistons movable within corresponding compression cylinders. A blower wheel is concentrically mounted to the crankshaft adjacent the exterior of the crankcase. Each compression cylinder includes a thermally conductive cylinder insert which a bore in which the corresponding piston rides. A thermally conductive heat sink having a plurality of annular cooling fins is cast integrally to the outer diameter of each cylinder insert and connected to the crankcase such that the compression cylinders and the crankcase are completely enclosed. Each cylinder insert is made of an aluminium alloy, preferably having a low silicon content and a high melting point so that it can be insert cast within the cooling fin and anodized without degrading the surface finish of its inner bore.
