摘要： A module, a base module and a system which comprises a module and a base module includes a pump channel and a valve unit which is connected with the pump channel wherein a fluid can be pumped through the pump channel and the valve unit, wherein a first wall section of the valve unit is flexible. The pump module has a movable valve body arranged in the valve unit, wherein the valve body can occupy an idle position in which the valve body closes the valve unit to prevent fluid from passing through. The valve body can occupy an operating position in which the valve body allows the fluid to flow through the valve unit and in which the valve body can be put in operating position through a deformation of the first wall section of the valve bodies so that the fluid can flow through the valve unit.

摘要： A volumetric pump and method for displacing a predetermined quantity of fluid at a predefined cracking pressure, independent of supply and output pressures. The volumetric pump (30) includes an inlet cracking valve (46), an outlet cracking valve (52), and a plunger (48)for displacing fluid from a pumping portion (34b) of flexible tubing (34) that extends through the volumetric pump. The pumping portion of the flexible tube fills with liquid when the inlet cracking valve is fully opened and is urged to expand by jaws (236) on pivotally-mounted arms (234). The arms are forced to pivot, as tubing reshaper rollers (160), disposed on the plunger, roll along the inner surface (232) of each arm. During a pumpback-pressurization segment of the pumping cycle, the inlet cracking valve applies a cracking force to the flexible tubing, while the plunger compresses the pumping portion of the flexible tubing sufficiently to develop a cracking pressure that displaces excess fluid back through the inlet cracking valve toward a container (32). After the excess fluid has been forced from the pumping portion of the flexible tubing, a pumping segment of the cycle begins, wherein the inlet cracking valve closes fully and the outlet cracking valve applies a cracking force to compress the flexible tubing. Fluid is then forced by the plunger from the pumping portion of the flexible tubing into a distal portion (34c). The volumetric pump compensates for variations in elasticity of the flexible tubing that would otherwise cause variations in the cracking pressure, using balance blocks (42 and 58).

摘要： A chamber of a peristaltic pump is described wherein a segment of the stator is removed so that said chamber containing the rotor and resilient tube may be stored with the resilient tube not pinched by the eccentric rotor. When the chamber is to be used, a cap is snapped over the chamber which completes the missing segment of the stator and the rotor is engaged to the motor shaft. When the rotor turns in the stator with all segments snapped together, liquid is conducted from inlet to outlet ports.

摘要： A lubricating system for a chain saw which includes a circular single-lobed cam on the sprocket drive shaft surrounded by an anti-friction bearing. The outer race of the bearing engages a Cshaped loop of flexible tubing progressively to produce peristalic action between the input end of the tubing which is connected to an oil reservoir and the output end which leads to the chain. The output has an adjustable restriction in the form of a throttling valve and an associated bypass line which shunts most of the oil back into the reservoir. The loop of tubing extends about the shaft substantially less than a full revolution and the eccentricity is limited so that the tubing is continuously open throughout its length during at least a portion of each revolution of the drive shaft for impositive pumping of the oil against the restriction for achieving an extremely low but reliable flow rate.
