Abstract
A device and method for producing pulsating waves of energy for the massaging effect normally associated with high pressure jet systems in whirlpools, pedicure spas, bathtubs and other medical and non-medical devices. The jet assembly includes no external pipes and unlike “pipeless” jet assembly systems in use today, does not require disassembly or circulation of chemical cleaning agents to maintain a sanitary condition of the jet assembly.
Claims20
A water jet assembly comprising:
- a faceplate that defines an inlet and an outlet;
- a base constructed to cooperate with the faceplate;
- a diaphragm disposed between the base and the faceplate and configured to cooperate with the faceplate to be movable between a first position wherein the diaphragm interferes with passage of a fluid through one of the inlet and the outlet and a second position offset from the faceplate to define a volume therebetween;
- and
- an exciter connected to the base and configured to excite the diaphragm to move fluid from the inlet to the outlet during operation of the exciter and such that the diaphragm occupies the volume when the exciter is off.
2 more elements
A water jet assembly comprising:
- a faceplate that defines a plurality of inlets that are oriented radially about at least one outlet;
- a housing constructed to cooperate with the faceplate;
- a diaphragm that is movable between a first position and a second position and disposed between the housing and the faceplate, the diaphragm obstructing the plurality of inlets and the at least one outlet when in the first position and defining a fluid passage between the diaphragm and the faceplate that extends between the plurality of inlets and the at least one outlet when the diaphragm is in the second position;
- and
- an exciter supported by the housing and configured to oscillate the diaphragm between the first position and the second position to move fluid from the plurality of inlets to the outlet via the fluid passage during operation of the exciter and such that the diaphragm obstructs the plurality of inlets and the at least one outlet when the exciter is off.
2 more elements
A method of forming a water jet flow, the method comprising:
- drawing water into a variable volume chamber of a jet assembly and expelling water out of the variable volume chamber of the jet assembly by operation of an exciter;
- and
- occupying a volume of the chamber with a diaphragm when the exciter is off.
