417274000 | CONDITION RESPONSIVE VARIABLE VOLUMETRIC CAPACITY EXPANSIBLE CHAMBER PUMP (I.E., CLEARANCE CONTROL) | 6 |
20120308409 | FLUID FLOW METER - A fluid flow meter comprising a fluid pump to displace fluid with pumping strokes of one or more pumping stroke types wherein each of the one or more stroke types displaces a known volume of fluid, a sensor functionally associated with a fluid reservoir and adapted to generate a signal indicative of a fluid pumping condition within the fluid reservoir, which fluid reservoir is integral or functionally associated with the pump, and circuitry to trigger one or a sequence of strokes of the pump in response to a signal from the sensor. | 12-06-2012 |
20130259714 | Variable Displacement Compressor - Overpressure of refrigerant in a refrigerant circuit is avoided. A swash plate type variable displacement compressor includes a muffler (muffler space | 10-03-2013 |
20160097386 | Displacement Pump - A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump. | 04-07-2016 |
20160160823 | HIGH PRESSURE PUMP - A high pressure fuel pump unit includes a pump head where an inlet channel opens into a low-pressure chamber itself in fluid communication with a compression chamber. A valve is arranged so that when it is closed the fuel fills the low-pressure chamber and when the valve opens the fuel flows from the low-pressure chamber into the compression chamber. The pump head also includes a resilient member arranged so that when the valve is closed, the resilient member deforms to increase the volume of the low pressure chamber. When the valve opens, the fuel flows into the compression chamber, pushed by the resilient member which takes back its original shape. | 06-09-2016 |
