## Abstract

A hydraulic pressure amplification system for increasing the output pressure in the delivery pipe to or from a ram pump, a spring rebound inertia pump or similar cyclic pumps which deliver a pulsating flow. Said hydraulic pressure amplification system comprises a fluid inlet (29), a fluid outlet (30) and one or more rigid bodies (21) which contain an enclosed convolute passageway extending between the fluid inlet and the fluid outlet. The body or bodies are sandwiched between rigid cover plates (22,23) which respectively contain the fluid inlet (29) and the fluid outlet (30).

## Claims

### Claim 1

A pulsed hydraulic pressure amplification system characterised by a pressure matrix having a fluid inlet and a fluid outlet (9, 10; 29, 30; 45, 46) and a rigid expansion-resistant body which contains an enclosed convolute passageway (4; 26; 47) extending between the fluid inlet and the fluid outlet, and wherein the expansion-resistant body comprises a matrix portion (1; 21; 41) which forms the enclosed convolute passageway (4; 26, 47) and a rigid outer portion (2, 3; 22, 23; 42) which encloses the matrix portion.

### Claim 2 (depends on 1)

A pulsed hydraulic pressure amplification system according to claim 1 in which the rigid outer portion comprises a pair of end cheeks (2, 3; 22, 23) which hold the matrix portion (1; 21) between them.

### Claim 3 (depends on 2)

A pulsed hydraulic pressure amplification system according to claim 2 in which the end cheeks (2, 3; 22, 23) are connected together by tie elements, e.g. machine screws (7).

### Claim 4 (depends on 3)

A pulsed hydraulic pressure amplification system according to claim 3 in which the tie elements (7) are inserted through the matrix portion (1; 21).

### Claim 5 (depends on 1)

A pulsed hydraulic pressure amplification system according to claim 1 in which the matrix portion comprises a plurality of matrix bodies (21) which each define a section (26) of the convolute passageway.

### Claim 6 (depends on 5)

A pulsed hydraulic pressure amplification system according to claim 5 in which the matrix bodies each comprise a single end wall (25) and a side wall (24) which defines the passageway section (26).

### Claim 7 (depends on 6)

A pulsed hydraulic pressure amplification system according to claim 6 in which the passageway section (26) is exposed at an open end of the body.

### Claim 8 (depends on 6)

A pulsed hydraulic pressure amplification system according to claim 6 in which the end wall (25) contains a single port (27) which communicates with the passageway section (26).

### Claim 9 (depends on 7)

A pulsed hydraulic pressure amplification system according to claim 7 in which the matrix bodies (21) are held together with the open end of one body covered by the end wall (25) of an adjacent matrix body.

### Claim 10 (depends on 5)

A pulsed hydraulic pressure amplification system according to claim 5 in which the passageway section (26) is substantially part-circular and extends through 270 degrees.

### Claim 11 (depends on 5)

A pulsed hydraulic pressure amplification system according to claim 5 in which the matrix bodies (21) are arranged in a stack between a pair of end cheeks (22, 23).

### Claim 12 (depends on 1)

A pulsed hydraulic pressure amplification system according to claim 1 in which the fluid inlet and outlet (9, 10; 29, 30; 45, 46) are fixed to the rigid outer portion (2, 3; 22, 23; 42).

### Claim 13 (depends on 1)

A pulsed hydraulic pressure amplification system according to claim 1 which includes a plurality of pressure matrixes (100) connected in series.

### Claim 14 (depends on 1)

A pulsed hydraulic pressure amplification system according to claim 1 in which the pressure matrix (100) is connected to a port of an oscillating pump (110) or fluid pressure amplifier (101).
