Abstract
In a fluid pump or motor improvements are provided to the piston shoes therein to permit a higher pressure in the respective device. Other improvements are done to the hydrostatic bearings in radial piston or radial chamber type fluid motors and pumps. A further arrangement is, that plural pistons are applied to permit the use of two different fluids in the respective device. This leads also to the application of disc springs and their modification in a pump or motor to make the pumping of non-viscous fluids like water possible at very high pressure. Motors are provided with arrangements to permit them to drive and to carry simultaneously or to have hollow shafts, whereby improved and novel machines and vehicles are obtained.
Claims9
A fluid machine for the intake and explusion of a fluid, comprising, in combination, a first body (98), a second body (99), a control body (102), passages, working chambers which periodically increase and decrease their volumes, and an improvement, wherein said improvement includes:
- (a) passages (161) through said first body to port into holding recesses (22) which are provided in said first body,
- (b) a piston shoe guide face (156) provided on said second body,
- (c) pistons 36, piston shoes 21 and coned rings 1,2 provided between said first and second bodies with partial extension of said pistons into said holding recesses, with said
- (d) piston shoes provided between said pistons and said second body, and with said coned rings comprising
- (e) at least one hollow coned ring, which has a medial bore, between a portion of a respective piston and a respective holding recess of said holding recesses,
- (f) passages through said piston and through said piston shoes to port into pockets of hydrostatic bearings between said piston shoes and said guide face,
- wherein one of said bodies moves respective to the other of said bodies to provide a periodic compression and expansion of said coned rings whereby said coned rings provide said working chamber and take in and expell fluid from and to respective ports in said control body, wherein said piston forms a head portion and a therefrom axially extending pipe portion with said head portion extending radially outwards beyond said pipe portion, and, wherein said pipe portion is inserted into the medial bore of said hollow coned ring.
