| PROBLEM TO BE SOLVED: To provide a gas compressor having a case not to depend on the specifications of a gas compressor, and to reduce cost, facilitate casting and machining, and reduce incurring of a loss due to a casting defect and a machining miss. SOLUTION: A compressor body is securely inserted in a case, and the case is divided into a front casing 91 independent corresponding to the number of the compressor bodies, and a rear casing 53 having a discharge chamber and a discharge port. The front casing 91 is provided with an inner wall machined with high precision so that airtightness between the compressor body and the front casing is kept. Meanwhile, a rear casing 53 does not demand for special precision. Flanges 93A and 93B capable of being coupled with each other are disposed at the division end part of the rear casing 53 and the division end part of the front casing 91. | ||||||

| PURPOSE: To provide a shaft seal which is easy to remove and replace, and protect a shaft bearing from being damaged by hydraulic fluid. CONSTITUTION: A hydraulic fluid pressure energy translating device 10 of the sliding vane type comprises a cam ring 13 including an internal contour, a rotor 35 having a plurality of vanes 36 and a slideable cartridge 12. One or more pumping chambers are defined between the periphery of the rotor and the internal contour of the cam through which the vanes pass carrying fluid from an inlet port 19 to an outlet port 22. Two pressure chambers are formed for each vane and each vane has two surfaces one in each chamber, both being effective under pressure in the respective chambers to urge the vanes into engagement with the cam. The cartridge includes two support plates 14, 15. One of the plates supports an annular shaft seal 41 that engages a shaft rotatably mounted in a housing 11 and supporting the rotor such that when the cartridge is removed from the housing, the shaft seal is simultaneously removed.

| 125 | Vane pump with adjustable delivery volume | US15305973 | 2015-02-17 | US10125764B2 | 2018-11-13 | Johannes Burdiak; Richard Vogt; Uwe Zellner |
| The invention proposes a vane pump (VP) with adjustable delivery volume, which vane pump has a pump housing (G), a cam ring (KR) arranged therein, and a rotor (R) which is rotatably movably mounted therein. The vane pump (VP) has a regulating device (RV) through which the delivered pressure medium (DM) flows and which has two outlets (A1, A2) which are each connected to one of two pressure chambers (DK1, DK2) in order to charge these with regulable proportions of the pressure medium (DM), wherein, to change the eccentricity of the cam ring (KR) relative to the rotor (R), the two pressure chambers (DK1, DK2) act on the outer surface of the cam ring (KR). The vane pump (VP) has two criss-crossing control ducts (STK*, STK#) which connect in each case one of the outlets (A1, A2) to one of the two pressure chambers (DK1, DK2) in order to charge these with the regulable proportions of the pressure medium (DM). The criss-crossing control ducts (STK*, STK#) are preferably arranged in a cover (D′) of the pump housing such that the control ducts (STK*, STK#) are in a criss-crossing arrangement without coming into contact with one another. By means of this design, the vane pump (VP) can be easily reconfigured for a change in rotational direction of the rotor. | ||||||
