| Number | Title | Issue Date |
| 7156190 | Impact tool An impact tool has a slidable hammer that is driven by hydraulic oil under pressure inside a chamber. The hydraulic oil is pressurized by a piston driven by compressed gas on the opposite side of the piston from the hydraulic oil. The gas in the gas chamber is compr... | 01/02/2007 |
| 5159814 | Pneumatic impulse motor with gas cushion An impulse motor for a hand held hammer machine comprises a housing (10) with a cylinder (11) therein, in which a reciprocating drive piston (40) via a gas cushion in a working chamber (44) of said cylinder (11) repeatedly drives a hammer piston (15) to i... | 11/03/1992 |
| 4932479 | Vacuum-compression type percussion power tool with a pumping chamber A vacuum-compression type percussion power tool comprises a housing (12), a cylinder (14) fixed in the housing, a piston (16) reciprocating in the cylinder (14) from a reciprocating drive mechanism such as a crank mechanism (18) driven by an electric moto... | 06/12/1990 |
| 4828046 | Vacuum-compression type percussion power tool with an auxiliary chamber A vacuum-compression type percussion power tool comprising a housing (12), a cylinder (14) fixed in the housing, a piston (16) reciprocating in the cylinder (14) from a reciprocating drive mechanism such as a crank mechanism (18) driven by an electric mot... | 05/09/1989 |
| 4823886 | Vacuum-compression type percussion power tool A vacuum-compression type percussion power tool comprising a housing (12), a cylinder (14) fixed in the housing, a piston (16) reciprocating in the cylinder (14) from a reciprocating drive mechanism such as a crank mechanism (18) driven by an electric mot... | 04/25/1989 |
| 4346768 | Impact device with sinusoidal rotary-to-reciprocative converter The rotary output of the power source of an impact device is converted to reciprocation of a body, preferably having a resilient coupler, which drives a ram into impacting in an improved rotary-to-reciprocative motion converter including a crankshaft oper... | 08/31/1982 |
| 4149384 | Fluid pressure amplifier A fluid pressure amplifier for intensifying fluid pressure, the amplifier comprising a housing including a hydraulic fluid reservoir therein. A first chamber includes a slave piston mounted for reciprocation therein and for abutting engagement with a work... | 04/17/1979 |
| 4049078 | Marine acoustic pulse train signal generator An apparatus for generating a series of seismic acoustic pulses in a body of water. The series is characterized by having continuously-variable, non-repetitive time intervals between successive pulses during a continuous seismic recording. The preferred g... | 09/20/1977 |
| 4047849 | Pneumatic pulsator pumping system with pulsator fluid venting valve A pneumatic pump adapted primarily as a left ventricular heart assist device includes a flexible bladder with a rigid housing. A pneumatic driver applies rhymical pulses between the bladder and the housing to repetitively collapse the bladder and establis... | 09/13/1977 |
| 3948051 | Fluid pressure amplifier A fluid pressure amplifier for intensifying fluid pressure, the amplifier comprising a housing including a gas-hydraulic interface piston; a first chamber includes a slave piston mounted for reciprocation therein and for abutting engagement with a work pi... | 04/06/1976 |
