Pump

A connecting rod including a generally vertical oriented rod section having a piston end and a connecting end. A non-through bore formed in the connecting end receives a pin mounted eccentrically on a shaft, such that rotation of the shaft causes the rod section to reciprocate. An axial groove formed in the bore allows air in the bore to escape during assembly. When a lubricant is disposed in the bore, the groove also provides lubrication over the entire length of the pin.

Connecting rod with integral grease reservoir

A connecting rod including a generally vertical oriented rod section having a piston end and a connecting end. A non-through bore formed in the connecting end receives a pin mounted eccentrically on a shaft, such that rotation of the shaft causes the rod section to reciprocate. A bleed hole formed in an inside end of the bore allows air in the bore to escape during assembly. When a lubricant is disposed in the bore, the bleed hole is shaped to inhibit an excess amount of lubricant from escaping therethrough.

Compressor assembly

A compressor assembly including a motor having a rotatable shaft, and a bracket attached to the motor. The bracket has fingers extending substantially perpendicular to the shaft. The fingers having ends with engagement surfaces. A connecting rod has a connecting end eccentrically connected to the shaft, and a piston end received in a cylinder sleeve. The cylinder sleeve is supported by shelves projecting from the fingers and is interposed between the fingers. A valve head member disposed above and in sealed engagement with the cylinder sleeve is interposed between the fingers, and the finger engagement surfaces retain the valve head member in sealed engagement with said cylinder sleeve.

A pressure relief valve assembly for relieving fluid pressure in an exhaust outlet includes a deformable fluid passage in fluid communication with the exhaust outlet. The passage is blocked by a poppet disposed in the passage for discouraging fluid firm passing therethrough. A spring disposed in the passage urges the poppet against the fluid, and a knob having external buttress threads is disposed in the passage to compress the spring. The knob compresses the spring to prevent fluid below a predetermined pressure from escaping through the passage past said poppet.

Pressure relief valve assembly

A motor and reciprocating piston assembly is mounted in housing halves using elastomeric mounting members interposed between the assembly and each half. There are three spaced sleeve-like mounting points on each side of the assembly and three similarly spaced sleeve-like bosses on the housing halves. The mounting members have three mounting portions received in the mounting points and bosses. The three mounting portions are connected by integral arms.

Mounting for air compressor

Air compressor

A valve assembly for a pumping apparatus includes a cylinder sleeve having a head end with inlet and outlet ports surrounded by a recess. An elastomer seal element is received in the recess and includes a peripheral portion that encircles the ports and a bridge portion that extends across the space between the ports. Integral flapper valves extend into the spaces between the peripheral portion and the bridge portion. A valve head with inlet and exhaust chambers has a flat surface that seats against the seal element. The cross-section of the peripheral and bridge portions are compressible, such as that of an O-ring.

Valve assembly

Cabinet for nebulizer

Head for compressor

A valve plate assembly is provided with a valve restraint for maintaining a valve within a recessed portion of the valve plate. The valve restraint further includes an irregular surface which contacts the surface of the valve when the assembly is in use, for example, in a compressor. The irregular surface may include through-holes at least partially through the surface which contacts the valve or may be a textured surface which contacts the valve during use. The valve plate includes a recessed portion having guides for receiving notched sections in the sidewalls of the valve and valve restraint.
