Rotary Piston Pumps TRIZ Cases

Optimizing the included angle between the volute and outlet bend reduces airflow losses by up to 20% while maintaining manufacturing simplicity.

Communication channels in a reservoir-based noise-reduction mechanism dissipate oil pulsations, smoothing pressure transitions and lowering engine whining.

A detachable reservoir pre-filled with precise oil quantities simplifies servicing through a snap-off suction line mechanism.

A desmodromic radial vane pump merges two fluid inlets into one unit to halve component count.

A connecting duct introduces air into the suction chamber to equalize pressure, preventing oil contamination during pump shutdown.

An integrated screw diverts process fluid to lubricate bearings, eliminating external circuits and reducing device complexity.

Gerotor pump preloads vane cell vanes against the stroke ring, eliminating startup inefficiencies and reducing system complexity.

An eccentric pocket with integrated port plates directs hydraulic fluid flow while reducing seal count to improve sealing efficiency.

A pump adjusts delivery volume using dual setting chambers and an electromagnetic valve for precise fluid control.

Correcting inner rotor tooth profiles in circumferential and radial directions increases oil pump discharge capacity without enlarging the rotor size.

Internal oil supply passages route lubricant directly to rotor sliding surfaces, reducing power consumption caused by excess fluid blocking rotation.

A submersible pump integrates a fluid filter with a sealed rotor cover to protect circuitry from liquid exposure.

A vacuum pump channel outlet sits below the minimum oil level in the sump to guide operating medium directly into the liquid.

A variable displacement oil pump adjusts internal pressure via a control valve to regulate discharge volume.

A compact hydraulic control valve manages oil flow across rotational speeds using integrated lands and a small-diameter connecting portion.

A nozzle arrangement directs a jet stream at an acute angle into a mixing chamber to create a common flow for dual suction pockets.

Segmented economizer ports on both rotor sides resolve pressure interference from clustered openings, improving gas flow without altering compression timing.

An internal recess with an antechamber supplies constantly exchanged fluid to a gear pump shaft seal, preventing premature wear from problematic fluids.

An intermediary chamber buffers vacuum fluctuations, preventing external air contamination while maintaining consistent product filling.

An adjusting device rotates and displaces axially arranged gears to optimize suction capacity.

Inclined bottom walls at outlet openings direct gas flow to reduce noise and deflagration while improving suction pressure.

Integrally formed extruded aluminum housing consolidates oil separation chambers, reducing device complexity while maintaining functional flexibility.

Relocating the connector box to the pump cover allows a bus bar to pass through a penetration hole, providing space for electrical configuration.

Pneumatic actuation replaces electromagnetic valves to ensure reliable check valve closure at low pressures without external power.

A variable output pump uses a differential linkage to mechanically couple control and main stage pumps for fluid flow adjustment.

A pump body assembly uses a sliding block structure with a connecting portion and two sliding sub-blocks to form a variable volume cavity.

A motor control device applies a predetermined drive pattern to an electric motor based on initial driver circuit unit temperature.

A dry vacuum pump uses a smooth belt drive to rotate parallel rotor shafts without lubrication.
