Positive Displacement Pump Components TRIZ Cases

Motor protrusion engages supporting plate orifice to reduce volume while maintaining attachment stability.

Control module starts gasoline engine on trigger pull and shuts it off after inactivity to prevent pump overheating.

Overmolding fuses the plastic cylinder head with the metal valve table to eliminate thermal deformation gaps that cause refrigerant and heat leakage.

A high pressure fuel pump plunger integrates an inner chamber and check valve assembly to control fluid communication between compression and inner chambers.

A one-piece plastic inlet valve element separates into cover and seat components during assembly.

An elevated damper cover uses alternating concave and convex regions to scatter structure-borne noise from high-pressure pump pulsations.

A linear compressor uses a refrigerant gas bearing to eliminate oil friction and a plate spring stopper to stabilize the discharge valve.

Multi-row bearing holes supply compression gas to stabilize the piston, while dual shells attenuate operational vibration.

A pump body design enabling piston rotation relative to the cylinder while reciprocating along the axis.

A bilge pump safety system uses a primary and monitor float switch to detect operational failures through state comparison.

Segmented wrist pin passageways route pressurized air through the bearing to dissipate frictional heat, resolving insufficient cooling in oil-free compressors.
