摘要： A fluid flow regulator and indicator device includes a housing connected between a source of fluid under pressure, such as a fuel pump, and a device to which fuel is supplied, such as a carburetor. The housing includes a pair of flexible diaphragms providing opposite movable walls of a sealed fluid flow passage through the housing. Separate biasing springs between each diaphragm and the housing adjust the position of the diaphragms in response to fluid flow through the passage to dampen fluid pulses entering the passage and provide a steady flow of fluid through the outlet of the passage. The biasing force of one spring is greater than that of the other spring, so that one diaphragm responds to a range of low fluid pressures existing in the system, and the other diaphragm responds to a range of high pressures in the system. Separate movable indicator arms connected to the diaphragms extend through opposite side walls of the housing. Each indicator arm responds to movement of its corresponding diaphragm and biasing spring to move away from the housing as fluid pressure in the passage increases to provide a reading of the fluid pressure in the system.

摘要： The pump has a casing accommodating a piston and a driving part. The casing has a first casing member having a driving part retaining portion retaining the driving part, a second casing member fixedly stacked on the first casing member in the reciprocating direction of the piston, and a cylindrical pump chamber peripheral wall member disposed around a head of the piston. The second casing member has an end wall portion extending in a transverse direction substantially perpendicular to the reciprocating direction. A pump chamber, a delivery chamber, and a buffer chamber are defined between the first casing member and the end wall portion of the second casing member. The pump chamber, the delivery chamber, and the buffer chamber are disposed side-by-side in the transverse direction.

摘要： Replaceable wear inserts of a material resisting abrasive wear due to particulates within pumped fluid are used for the inlet and/or outlet of a pulsation dampener coupled to the outlet of a land-base or mobile-mounted pump. The wear inserts may be integrated with pressure orifice devices contributing to pressure pulsation dampening. The wear inserts may have internal passages or be mounted to create turbulent flow through the pulsation dampener to mitigate the risk of dead spots accumulating particulates. The wear inserts may be sized for either “loose” or “tight” fit within the inlet and outlet to facilitate removability despite the potential for particulates embedding within the gap. Grooves may be provided with O rings to seal against pressure leaks.

摘要： A passive, self-regulating valve includes a static pressure chamber and an elastically collapsible tube supported within the static pressure chamber. The elastically collapsible tube is defined by a geometry that determines an activation pressure of the valve. The passive, self-regulating valve also includes a flow restrictor in fluid communication with the elastically collapsible tube inside the static pressure chamber, as well as piping connecting a source of pressurized liquid both to the flow restrictor and to an opening into the static pressure chamber. The piping enables the flow restrictor to control flow rate of the pressurized liquid through the valve independent of the activation pressure of the valve. In a preferred embodiment, the flow restrictor is a needle valve.

摘要： A pulsation dampener system is provided. The pulsation dampener system includes a pump that pumps fluid through the pulsation dampener system. A pulsation dampener is located downstream from the pump and dampens pulsations within the fluid. A pressure sensor is located downstream from the pump and detects a pump pressure of the fluid at the pulsation dampener. A wye pipe located downstream of the pulsation dampener and the pressure sensor that diverts the fluid into two or more flow paths. From the wye, a first flow path increases pump pressure of the fluid and a second flow path allows the fluid to flow unrestricted. Piping receives the fluid from the first flow path and the second flow path and discharges the fluid further downstream.

摘要： A damping device for damping or avoiding pressure surges, such as pulses, in hydraulic supply circuits has a damping housing (1) surrounding a damping chamber and having a fluid inlet (35) and a fluid outlet (41). A fluid receiving chamber extends between the fluid inlet (35) and the fluid outlet (41). During operation of the device, a fluid flow crosses the damping chamber in a throughflow direction (11), from the fluid inlet (35) to the fluid outlet (41). Parts of the fluid receiving chamber extend transversely with respect to the throughflow direction (11). More than one fluid receiving chamber is arranged one after the other in the throughflow direction (11). The fluid receiving chamber that is first upstream and the fluid receiving chamber that is last downstream immediately adjoin the fluid inlet (35) and the fluid outlet (41), respectively.
